Wed, 08 Feb 2012 14:35:37 +0100 Acute conditions affecting the perinephric space: imaging anatomy, pathways of disease spread, and differential diagnosis http://www.medworm.com/index.php?rid=5648726&cid=s_33410_14_f&fid=33410&url=http%3A%2F%2Fwww.springerlink.com%2Fcontent%2Fl6hv14823j416381%2F Abstract  The perinephric space is an important, central compartment of the retroperitoneum which may host various acute conditions. Imaging evaluation of the perinephric space requires an understanding of its anatomy and the pathways of disease spread to and from other retroperitoneal compartments. Numerous acute conditions can affect the perinephric space and may occur in isolation, extend from nearby retroperitoneal structures, or be part of a systemic condition. Familiarity with the key imaging findings of acute conditions affecting the perinephric space is imperative to facilitate diagnosis and guide treatment. The purpose of this article is to review and illustrate the relevant anatomy, pathways of disease spread, and acute pathology encountered during cross-sectional...

However, missing or misdiagnosing this entity on clinical evaluation and/or imaging has significant implications for patients as they may undergo unnecessary surgery for suspected testicular torsion or tumor. Knowledge and recognition of the features of segmental testicular infarction on ultrasound and MRI will aid in the diagnosis of this disease early in the patient’s course. The common imaging features of segmental testicular infarction and the clinical literature are reviewed, with an emphasis on ultrasound, utilizing seven recent cases from three institutions.

Intussusception is classified according to location, etiology, and to the presence or not of a lead point. We illustrate several causes of AI with a variety of radiological findings on plain film, ultrasonography, computed tomography, magnetic resonance, and endoscopy seen at our institution. Imaging plays a major role in their diagnosis and in determining the appropriate treatment.

We identified a need to examine tablet display performance prior to their use in preliminary interpretation of radiological images. We compared the spatial and contrast resolution of a commercially available tablet display with a diagnostic grade 2 megapixel monochrome LCD using a contrast detail phantom. We also recorded reporting discrepancies, using the ACR RADPEER system, between preliminary interpretation of 100 emergency CT brain examinations on the tablet display and formal review on a diagnostic LCD. The iPad display performed inferiorly to the diagnostic monochrome display without the ability to zoom. When ...

Therefore, imaging has evolved to play a pivotal role in the emergency setting. While appendicitis is a common cause for acute pain, there are numerous other important differential considerations with which the radiologist must be aware. The purpose of this review is to list an anatomy-based, encompassing differential diagnosis in addition to acute appendicitis for right lower quadrant pain; demonstrate the key imaging findings of numerous differential considerations; and describe helpful imaging and clinical features useful in narrowing the differential di...

Recognition of adrenal hematomas is complicated by the variable appearance of these lesions. We survey the ways in which adrenal hematomas can appear on CT and provide strategies for differentiating hematomas from other adrenal pathologies.

It is an easily learned tool that can be conveniently and speedily applied in the fragments injury. We describe the detailed technique of performing MPRs, depicted by various examples. Furthermore, benefits and limitations of the technique (such as numerous fragments, change in position and respiratory phase, and embolization of fragments) are presented. We conclude that MPRs in the fragments trajectory can be helpful for accurate and fast diagnosis of injury. In addition, MPRs serve as a vivid presentation of injured and spared organs.

A case report http://www.medworm.com/index.php?rid=5251189&cid=s_33410_14_f&fid=33410&url=http%3A%2F%2Fwww.springerlink.com%2Fcontent%2F3367r1k21gq328v2%2F We report a unique case of a humeral medial condyle fracture in a 15-year-old boy with posttraumatic fishtail deformity. The fracture line extended up from the top of the sharp trochlear wedge to the incomplete medial supracondylar cortical aperture. The appearance of the upward displacement and computed tomography imaging with three-dimensional reconstruction at the two different elbow positions suggested that an edge of the semilunar notch of the olecranon acted as a wedge to break and split the trochlea directly. This is the first visualized case of a wedge type injury and may provide evidence that humeral medial condyle fractures can be produced by the wedge force besides the valgus avulsion one.

The rarity of this finding is probably secondary to the extensive necrosis of bone marrow that needs to occur at a rapid phase for the fat to accumulate. However, an extra-osseous fat fluid level is a specific diagnostic sign of osteomyelitis in cases with otherwise equivocal imaging findings and should be reported as such, especially when associated with medullary bone destruction and in the absence of trauma.

Unlike the carotid arteries, the vertebral arteries receive collateral blood flow through ascending cervical branches in addition to a convergent arterial supply with the contralateral vertebral artery. We hypothesize that the incidence of stroke after vertebral artery injury is less than after carotid artery injury in part because of reconstitution of vertebral arteries by cervical collaterals. A retrospective blinded interpretation of angiographic studies in 46 patients with blunt vertebral injury was performed to assess for presence and grade of vertebral artery injury and for the presence of reconstitution of the vessel v...

Multi-center search yielded 11 adults with symptomatic splenic injury related to colonoscopy. Workup included abdominal CT in 10 (91%) cases and abdominal radiography in two patients (one patient had both). Colonoscopy findings, post-procedural course, and CT findings were systematically reviewed. Mean patient age was 62.2 years (range, 51–84 years); 8 (73%) of 11 were female. The majority (64%) of colonoscopies were for screening. No immediate complications were reported at optical colonoscopy; tortuosity/redundancy was noted in five cases. Except for a small (8&...

This sign has the advantage of early appearance, side-to-side comparison, and high conspicuity. Two of the presented cases demonstrate the CB sign in the absence of other established signs typically seen with early cerebral infarction. Five additional cases demonstrate this sign in conjunction with previously described criteria. The CB sign may allow earlier detection of hyperacute infarction leading to more rapid initiation of thrombolytics to minimize ischemic injury.

The study took place at a large, urban pediatric teaching hospital. Demographic and imaging data of all patients who underwent both US and CT examinations within a 72-h period to evaluate for appendicitis were assessed. Two hundred eighteen patients met study criteria. Greater abdominal wall fat (p < 0.001) was observed in the subjects where the appendix was not visualized with ultrasound (17.04 mm, SD ± 13.52) than in subjects where the appendix was visualized with ultrasound (11.75 mm, SD ± 11.81) was significant.

Although many published articles provide trainees with the means to correctly interpret imaging studies, they do not provide a framework for understanding why and how errors occur. In this article, we propose a classification system that allows categorization of errors, which we hope can serve as a basis for peer review, self-education, and quality improvement programs. Our scheme incorporates elements of a classification system proposed by previous authors but also includes novel categories. In this article, we show the usefulness of our scheme by applying it to a specific, and particularly problematic, diagnosis in emergency radiology, namely that of dural sinus thrombosis. Content ...

Three hundred and nine consecutive shoulder MRI studies (185—male, 124—female, 50 ± 15 years old) were retrospectively evaluated for findings suggestive of synovial injury including rupture and/or diverticulum of the joint capsule, bursa, and biceps tendon sheath (BTS), ganglion/synovial cyst, geyser phenomenon, and sequel of previous shoulder dislocation (Hill–Sachs deformity). Patients with one or more of these findings were included in the MR-positive group, whereas the remaining subjects were used as MR negatives. Based on their medical records, patients were also div...

Although MDCT is highly sensitive and specific for bony injuries, errors in diagnosis can still occur. Knowledge of the possible imaging pitfalls on MDCT, leading to either misdiagnosis of fractures or missed fractures, is vital in ensuring an accurate diagnosis. This paper serves to highlight conditions that can mimic or reduce the sensitivity for the detection of acute spinal injuries, as well as demonstrate imaging findings which aid in the detection and diagnosis of subtle spinal injuries. Review areas for clinically relevant extra-spinal findings in the context of trauma will a...

In addition, an underappreciated contributor to the acute abdomen is oncologic disease and its treatment. Oncologic patients are at increased risk in the development of numerous acute abdominal conditions due to a combination of tumor invasion, sequelae of treatment, and altered immune response. Cross-sectional imaging of the oncologic patient poses several unique challenges due to the need to be able to evaluate surgically altered anatomy, evaluation of treatment response, and potential untoward effects of neoplasia and its treatment. The radiologist plays a pivotal role in the multidisciplinary approach t...

The abdominal CT scans of 90 patients were retrospectively reviewed by three radiologists: an abdominal imaging specialist, an experienced general radiologist, and a senior resident. Forty-seven patients had surgically proven intestinal ischemia and comprised the case group, while 43 patients had no evidence of intestinal ischemia at surgery and comprised the control group. Images were reviewed in a random and blinded fashion. Radiologists’ performance in diagnosing bowel ischemia from other bowel pathologies was evaluated. The sensitivity, specificity, and accuracy for diagnosing bowel ischemia were 89%, ...

Our secondary aim was to determine if elderly intoxicated patients were more likely to have an intracranial injury. We identified patients suspected of alcohol intoxication who underwent CT scanning in the ED over a 4-year period. Pre-determined data elements including demographics, diagnosis, and disposition were extracted using a pre-formatted data sheet by blinded abstractors. “Positive” CT was defined as evidence of any type of intracranial hemorrhage. A total of 2,671 subjects with suspected alcohol intoxication and a head CT were identified. Fifty out of the 2,671 (1.9%) had a positiv...

CT and US exams of 70 patients who underwent MDCT for evaluation of abdominal/pelvic pain followed by pelvic ultrasound within 48 h were retrospectively reviewed by three readers. Initially, only the CT images were reviewed followed by evaluation of CT images in conjunction with US images. Diagnostic confidence was recorded for each reading and an exact Wilcoxon signed rank test was performed to compare the two. Changes in diagnosis based on combined CT and US readings versus CT readings alone were identified. Confidence intervals (95%) were derived for the percentage of times US reimaging can be expected to l...

Most data have been derived from CA victims of cardiac etiology, however, CT signs of brain ischemia/hypoxia have rarely been studied in victims of asphyxial CA. Loss of gray–white matter discrimination (GWMD) at the basal ganglia seems to be the most reliable early CT sign of brain ischemia/hypoxia; a retrospective study was conducted to clarify its incidence, prognostic significance, and temporal profile in resuscitated victims of CA by food asphyxiation. Brain CT scans of each victim were interpreted by two blinded observers. During a 5-year period, 39 resuscitated victims of CA by food asphyxiation underwent brain CT. Thirty-one (79%...

One hundred and fifty polytrauma patients (104 male, mean age 47 ± 19) underwent wbCT with arms elevated above the head (group A, n = 50), alongside the abdomen (group B, n = 50), and on a pillow ventrally to the chest with both arms flexed (group C, n = 50). Two blinded, independent observers measured image noise and rated image quality (scores 1–3) of the liver, aorta, spleen, spine, and lower lungs. Radiation dose parameters were noted, and the abdomens’ anterior–posterior diameter and scan lengths were measured. Interreader agreements for image noise (r =...

Although iatrogenic internal injuries related to manual CPR and CPR devices have previously been reported [1, 2], there has been no reported CT evidence of liver injury related to automated CPR devices to the authors’ knowledge. Imaging findings of complications related to the use of automated CPR devices are important to recognize and also help explain the possible mechanisms of injury. Liver injuries with active bleeding following CPR may have devastating consequences related to hemodynamic instability and may have an increas...

The study was carried out prospectively to assess the impact of an advanced radiographic study on the agreement of treatment plan and fracture classification of tibial plateau fractures. Eight experienced observers (six surgeons and two radiologists) classified 15 tibial plateau fractures with plain radiographs and CT scans and set up a treatment plan. Agreement was measured using kappa coefficients. Using plain radiographs alone, the mean interobserver kappa coefficient for classification was 0.47, which decreased to 0.46 after addition of CT sc...

Prolonged pain, swelling and disability sufficient to limit the activity and refractory to treatment following an ankle injury are not typical of an ankle sprain and should alert the clinician of the possibility of an alternative or an associated diagnosis. There are several conditions that can be misdiagnosed as an ankle sprain and those include ankle syndesmosis injuries, sinus tarsi syndrome, ankle and hind foot fractures, osteochondral lesions, posterior tibialis and peroneal tendons abnormalities, spring ligament damage, impingement syndromes and reflex sympathetic dystrophy. In this review, we discuss the imaging features of these conditions that can clinically mimic an ankle sprain. It is...

We conducted a retrospective analysis of all nontraumatic SAH who underwent a DSA between January 2006 and January 2010 and selected those with a PSAH pattern on CT done within 72 h from ictus. All CTAs were performed with a 64-section multidetector row CT scanner, and findings were compared with DSA and to follow-up imaging. Forty-nine patients with initial PSAH pattern and negative CTA who underwent subsequent DSA were identified. Six patients were excluded because CTA was not available in hospi...

Knowledge of common complications is important for the safe performance of loco-regional therapy (LRT) and for the interpretation of post-LRT follow-up imaging. With careful patient selection, LRT represents an effective and safe treatment of primary and secondary hepatic malignancies; however, complications related to LRT methods infrequently lead to additional morbidity.

Computed tomography (CT) was performed for surgical planning and demonstrated the additional finding of a radiographically occult nondisplaced fabella fracture. To the best of our knowledge, this is the first case in which CT documentation of a fabella fracture is reported. Fracture of the fabella is a rare but important clinical entity which may be overlooked clinically and radiographically. Clinical information can provide a high index of suspicion, and when coupled with radiographic and CT findings, may lead to the correct diagnosis. CT imaging of the knee may confirm a suspected fabella fra...

Initial review of systems and laboratory data were noncontributory. Non-contrasted CT demonstrated a large hyperdense mass centered in the suprasellar cistern without evidence of dissecting extra-axial hemorrhage. Though the initial appearance mimicked a basilar tip aneurysm or another primary extra-axial suprasellar pathology such as a hemorrhagic or proteinaceous craniopharyngioma, germinoma, or optic glioma, a second smaller, clearly intra-axial, hyperdense lesion was observed in the left periventricular forceps major white matter.

Given the universal usage of MDCT in assessing the liver in blunt abdominal trauma, reduction of patient dose is essential. The new l0se MDCT protocol presented here can achieve up to 50% dose reduction while maintaining diagnostic image quality and thus facilitate dose sensitive patient management. Our institution’s blunt hepatobiliary MDCT imaging algorithm can help determine which patients require operative therapy. Injury to the liver is graded on various schemes, one being the Organ Injury Scale devised by the American Association for the Surgery of Trauma classification based on the exten...

Heterogeneous early enhancement of the spleen and technical suggestions to minimize this artifact are discussed. Mechanisms of trauma and their classification under the American Association for the Surgery of Trauma are discussed and illustrated. The merits of an alternative classification system by Marmery et al. are also considered. We conclude that knowledge of the mechanisms, classifications, and grades of splenic trauma can assist the clinician in clinical decision making and promote improved patient outcomes.

It is more common in children compared to adults. Everyone should be aware of this entity to interact with clinicians to aid in triage and management of patients in view of poor prognosis. It is also important to prevent unnecessary laparotomies by confusing abdominal organ injuries. There are certain visceral and vascular findings described on abdominal CT that would alert the radiologist for this entity. This pictorial review should increase radiologists’ awareness and recognition of the CT manifestations of hypoperfusion complex before an irreversible state of shock occurs in blunt abdominal trauma.

We are reporting our experience with a case of blunt trauma to the chest, secondary to high-impact motor vehicle collision. The preoperative diagnosis of ascending aortic transection was made on subsequent imaging studies for which surgical repair was elected. Upon thoracotomy, a posterior pericardial tear was found to be associated with laterally displaced cardiac axis. Delayed levorotation of the cardiac axis in traumatic pericardial rupture is an uncommon finding and needs to be recognized in a timely manner.

Several imaging features have been described with multidetector computed tomography which allows the diagnosis of mesenteric ischemia with high sensitivity and specificity. However, there are imaging features which overlap with other pathologies including benign inflammation and infection. Knowledge of imaging findings in mesenteric ischemia and its potential mimics is important in early and definitive diagnosis.

Imaging confirmed subarachnoid hemorrhage in the spinal canal without intracranial hemorrhage. To the best of our knowledge this is the first described case report of subarachnoid hemorrhage in hemophilia A in the English literature. We also describe the anatomy and imaging features of hemorrhage in the different spinal canal compartments, including the subarachnoid space. Spinal canal hemorrhage in hemophilia is an emergency and serious condition and must be diagnosed and treated promptly. It is important to be aware of the diagnostic features of the spinal canal hemorrhage and carefully assess the spinal canal in hemophiliacs on cross-sectional studies. Content Type Journal Articl...

Clin Radiol 60:599–607, 2005). A significant number of these patients are haemodynamically unstable and can rapidly progress into shock and death. Recognition of computed tomography (CT) signs of imminent cardiovascular decompensation will alert the clinical radiologist to the presence of shock. In this review, the imaging findings of cardiovascular emergencies in both acute traumatic and non-traumatic settings with associated signs of imminent decom...

This technique is particularly useful in trauma patients for detection of skull base or calvarial fractures, thin tentorial subdural hematomas, or for more specific characterization of intracranial hemorrhage. The benefits of multiplanar reformations have been described for a variety of other diagnoses in the chest, abdomen, extremities, and spine, and their routine use continues to grow with the widespread availability of multi-slice CT scanners. In this article, we describe spiral head CT technique with multiplanar reformations as an alternative to the routinely used sequent...

We reviewed 58 clinical cases with acute ischemic stroke with CTP, compared the size of the area with long mean transit time (MTT) to that with abnormal intensity in magnetic resonance (MR) diffusion-weighted imaging (DWI) to diagnose penumbra, and compared the size of the area with reduced cerebral blood volume (CBV) in CTP to that in MR DWI to evaluate sensitivity for infarction. The total sensitivity of MTT to acute ischemic lesions was 81% (47/58). Sensitivity of MTT to segmental lesions was 100% (42/42) and for spot and focal lesions, 31% (5/16). In 13 patients, penumbra was diagnosed as lesions ...

His initial clinical exam and imaging studies of the head and cervical spine were negative. He subsequently developed nystagmus and a dedicated temporal bone study demonstrated a subtle fracture and vestibular pneumolabyrinth. Temporal bone fractures can be difficult to appreciate, and therefore, associated findings of fluid in the middle ear, stapes dislocation, or vestibular pneumolabyrinth must be carefully evaluated. Temporal bone computed tomography is a high resolution study, utilizing dynamic focal spot mode which leads to increased sampling and resolution, thereby reducing aliasing artifacts but a longer scan time and increased radiation dose.

While errors may be reduced by circumventing the traditional night call, there is limited evidence on the actual error rates of teleradiology groups. We have a comprehensive quality assurance (QA) process in our practice, which includes a review of discrepancies between preliminary reports and the final reports by the on-site radiologists. We analyzed the discrepancy QA data to determine the error rates. Archived QA data for 126,449 cases over a period of 1 year (2008) were analyzed for the discrepancy rate, nature of errors, and possible contributory factor...

The diagnosis of massive chylothorax with mediastinal shift was made on chest radiographs and CT scan. Initial investigations revealed no definite cause for the chylothorax. On later radiography and CT imaging with 3D surface rendering, a marked bone loss of the left ribs, clavicle, and shoulder joint was shown. The diagnosis of Gorham–Stout disease associated with chylothorax was suspected and histologically confirmed.

Though the final diagnosis was the same, each patient's symptomatology was different, mimicking more common pathologies. Thus, it is important to consider this entity when confronted with signs and symptoms of acute abdomen, especially in the elderly. A missed or delayed diagnosis can lead to costly erroneous studies, incorrect treatments and delay in proper management, resulting in significant morbidity and even mortality. The variety of presentations can often be misleading; therefore, a high index of suspicion is needed on the part of the Emergency Department physician and Radiologist.

Fifteen adult intensive care patients were examined with a standard-dose CT protocol (average radiation dose = 6.7 mSv), chosen as the reference standard, followed by a non-contrast-enhanced LDCT protocol (average radiation dose = 0.59 mSv). Each examination was then read by two separate groups of radiologists blinded to both the purpose and the protocol of the study. In the small group examined, the results showed 100% accuracy in the diagnosis of pneumomediastinum, pericardial effusion, and pleural effusion, and 90% accuracy in the diagnosis of pneumothorax and consolidation.

CT scans of 24 patients who had been imaged on two separate occasions for the evaluation of pancreatic pathology, once with water and subsequently with low-density barium sulfate as the neutral oral contrast agent were evaluated (total of 48 scans). Studies were randomized and reviewed in consensus on a workstation in the stack mode by two radiologists blinded to the type of oral contrast. The appendix was measured at baseline and 10 days later to obtain an average diameter. Results of the water and low-density barium sulfate groups were compared using paired t test. Contents ...

During a 5-year period from January 2004 to December 2008, our institution’s radiology department performed approximately 56,000 APCTs examinations in the ED. Sixty-eight percent of the APCT examinations used intravenous contrast. Nine hundred fifty-seven patients received two APCTs within 1 week for non-traumatic abdominal pain in the ED. Sixty-four patients with initially negative APCTs presented to the ED within 1 week with persistent abdominal pain and received follow-up APCT imaging. The mean follow-up period was 2.6 days.

Radiography sometimes cannot show fractures, especially those in costal cartilages, except for densely calcified ones. Several authors have recently investigated the role of ultrasound in the detection of rib fractures. We conducted this study to investigate possible rib fractures with ultrasound, determine those overlooked on chest x-ray, and analyze the possible clinical predictors of these insidious rib fractures in minor or mild blunt chest trauma. A total of 20 patients with minor mild blunt chest trauma were enrolled into this study. All radiographs were reviewed by two radiologists who noted rib fractures or other complications. Ultra...

The purpose of this pictorial essay is to present a series of cases of gastric pneumatosis, review the causes, and demonstrate how computed tomography (CT) can help guide management. A range of primary gastric pathology can cause air in the wall of the stomach. However, gastric pneumatosis may reflect intraabdominal pathology arising from other hollow viscera, with indicators of the extragastric etiology on CT.

Herein, we describe the case of a 76-year-old male who experienced an intracerebral hemorrhage subsequent to a fall and whose injury worsened over time. We summarize the current recommendations in the literature for when to initiate follow-up imaging in patients with traumatic head injury, the risk factors for progression, and the role of close clinical monitoring and serial imaging in managing such patients.

The diagnosis of subarachnoid hemorrhage (SAH) is usually the initial consideration before imaging is performed and, appropriately, must be quickly diagnosed. However, a number of entities can simulate SAH on imaging studies. Those entities are presented here. In addition, a number of disease processes other than SAH can produce worst headache of life. Some of the most important entities, and their CT and MR findings, are reviewed here. Content Type Journal ArticleCategory Review ArticleDOI 10.1007/s10140-010-0882-yAuthors James M.

Twenty-six cases of VoLumen-enhanced CT studies of the abdomen and pelvis were identified, of which 13 met the inclusion criteria. These were randomly matched to age control Gastrografin CT examinations. Appendiceal diameters (from wall to wall) were measured in three orthogonal planes and the average of these was recorded. We show that there is no statistical difference between normal appendiceal diameters in patients with a VoLumen-opacified ...

Levels of ADC decrease in infarcts were as follows: <20%, n = 9; 20–29%, n = 21; 30–39%, n = 25; 40–49%, n = 23; >50%, n = 16. For prediction of infarct age <24 h, sensitivity for the four ADC decrease thresholds ranged from 25% to 94%, specificity ranged from 10% to 85%, positive predictive value (PPV) ranged from 18% to 25%, and negative predictive value (NPV) ranged from 85% to 89%. For prediction of infarct age <48 h, sensitivity ranged from 23% to 98%, specificity ranged from 15% to 87%, PPV ranged from 46% to 56%, and NPV ranged from 60% to 89%.

We analyzed articles reporting the use of unenhanced CT in acute cerebral ischemia over the period 1976–2009 for frequency of the following brain parenchyma signs: loss of insular ribbon, obscuration of lentiform nucleus, sulcal effacement, and parenchymal hypodensity. We recorded data for the 2-, 3-, 6-, and 12-h intervals after symptom onset from various studies and (1) calculated percent of time intervals in which >50% of patients exhi...

We explore the diagnostic utility of early (less than a week) outpatient scheduled single photon emission computed tomography (SPECT) in intermediate-risk chest pain subjects who presented to EMD with non-diagnostic electrocardiogram and negative serum troponin level. Additionally, we intend to study the safety and cost-effectiveness of such a strategy. We conduct a prospective, non-randomized study of 108 subjects who fit the inclusion criteria. After SPECT studies, all subjects were evaluated in the cardiac clinic within 2 weeks of EMD visits. Final diagnosis of cor...

In seven domestic pigs, magnetic resonance imaging (MRI) was performed before (n = 7) and after (n = 5) APE was induced. Analysis of relative changes in right ventricular stroke volume (RVSV%), output (RVO%), end-systolic (RVESV%), end-diastolic volume (RVEDV%), and heart rate (HR%) was performed. Additionally, for the determination of the OS, all animals underwent contrast-enhanced CT–pulmonary angiography. The CT-based OS correlated strongly with RVSV% (r = 0.9576; p = 0.0104) and RVO% (r = 0.9703; p = 0...

It was suffered by a recreational fly fisherman who was hiking away from a casting spot when he fell and was impaled by a section of his graphite flyrod. The circumstances of his injury, its clinical manifestations, and its imaging findings are discussed. Emergency physicians and radiologists should be aware of the computed tomography appearance of impaled foreign bodies and their capability to penetrate deeply to reach critical vascular and neurologic structures. The role of imaging in penetrating trauma to the face and skull base for guiding appropriate intervention is emphasized.

To assess its diagnostic and prognostic significance, we have retrospectively evaluated 102 patients correlating the CT finding of gastrointestinal parietal gas with clinical data and outcome. Fifty-three patients (52%) had surgical evidence of intestinal infarction. In the remaining patients, a variety of lesions were found including intestinal obstruction, cancer, volvulus, ulcer, hernia, trauma, Crohn's disease, diverticulitis, and iatrogenic causes. We observed the presence of portal vein gas (PVG) associated to IP in 25.5% of cases. In patients having both IP and PVG, intestinal infarction was ...
