Mixed sclerotic and lytic lesions are seen in approximately one-third of cases, and in addition, partial epiphyseal involvement and periosteal reactions are also recognized. The aim of this case report is to describe Erdheim–Chester disease presenting with a destructive lesion in a metacarpal. To the authors' knowledge, this is the first time that the condition has been described with a purely lytic lesion within the peripheral appendicular skeleton.

A recognized complication of RYGB is the development of a transmesenteric internal hernia, in which a loop of small bowel herniates through a surgically created mesenteric defect. Although an internal hernia in this setting is challenging to diagnose clinically given the non-specific and often subtle presentation, a delay in diagnosis and operative treatment may result in dire consequences, including bowel incarceration, ischaemia, gangrene, sepsis, and possibly death. There has been increasing awareness by the radiology community of the risk of ...

Compared with more descriptive diagnostic names, eponyms can sometimes be confusing, especially to the novice. Adding to the confusion, eponyms are sometimes applied incorrectly. Nevertheless, their use remains common in the medical literature and clinical practice. Familiarity with H&N eponyms is important for accurate communication with radiology colleagues and clinicians. Some eponyms describe potentially fatal infections and their urgency should be appreciated. Other eponyms, such as those for inner ear congenital anomalies, are probably best avoided as they can be used imprecisely and cause confusion. This review summarizes the clinical and imaging findings of some common and important H&N ep...

They represent complete radial tears through the outer fibres of the annulus, although concentric and rim-type annular tears can give rise to similar appearances on magnetic resonance imaging (MRI). These classically occur in the midline but are also described posterolaterally and probably result from the action of flexional and rotational forces at the disc. Pain from these tears results from stimulation of the ventral ramus of the somatic spinal nerves, which supply the disc and nerve ingrowth in chronic disc disease mediated by substance P.

Although fewer than 120 cases have been reported in the literature since Green's initial description in 1832; on angiography, its incidence is estimated to be much higher—approximately 1 in 2000 individuals. Early diagnosis of PSA is critical because this vessel is prone to early atheromatous degeneration, thromboembolization, and aneurysm formation. Furthermore, undiagnosed PSA can mistakenly be injured during hip surgery or renal transplantation.

Computed tomography (CT) improves the learning of three-dimensional (3D) anatomy, and more recently multidetector CT (MDCT) technology has enabled the creation of high-quality reformations in varying projections. Multiplanar reformations (MPRs) of varying thickness in the coronal and sagittal projections can be created for direct correlation with findings on frontal and lateral chest radiographs, respectively. MPRs enable simultaneous visualization of the craniocaudal extent of thoracic structures while providing the anatomic detail that has been previously illustrated using cadaveric specimens.

However, CDC criteria remain reliable, allowing diagnosis of at least 75% of cases. The sensitivity of these criteria may be increased by including cases with persistent focal pulmonary opacification superimposed on diffuse nodularity.

Due to both an increase in the use of imaging, as well as advances in imaging technology, they are being increasing identified in the general population. As these lesions are benign, there is good evidence that the majority of them can be safely followed up without treatment. However, there is an increasing wealth of information available suggesting there are individuals with AMLs where prophylactic treatment is indicated to prevent complications such as haemorrhage. In such cases, treatment with radiological interventional techniques with subselective particle embolization has superseded surgical techniques in most cases. Even in emergency cases with catastrophic rupture, prompt emboliz...

They describe two cases where there was a decrease in FDG avidity within histologically proven sarcoid-like reaction following chemotherapy. This is contradictory to previously published data that has suggested that the stability of lesions on FDG-PET, despite therapy, may be used as a surrogate marker to identify this as sarcoid-like reaction rather than malignancy.

Prompt recognition maximizes the likelihood that surgery will be able to preserve fallopian tube viability and prevent secondary ischaemic injury of the ovary; however, the diagnosis is rarely established preoperatively as the presentation is non-specific with symptoms common to many other conditions. IFTT is particularly infrequent in the adolescent population with a review from 2008 identifying a series of only eight cases, in addition to 13 sporadic case reports. Furthermore, IFTT has never been reported in association with either a congenital uterine anomaly or renal agenesis.

It is due to a Gram-negative bacterium, Burkholderia pseudomallei which is an environmental saprophyte found in wet soils. Melioidosis is endemic to northern Australia and the Southeast Asia. However, there is now increasing number of reports of imported cases to regions where this infection has not been previously encountered. Almost any organ can be affected. Like many other conditions, radiological imaging is an integral part of the diagnostic workup of melioidosis.

According to the US National Hospital Ambulatory Medical Care Survey (NHAMCS), there were approximately 119.2 million ED visits (or 40.5 visits per 100 persons) during 2006. When compared with data of 1996, the ED visit rates have increased on an average of 32%. Unsurprisingly, the number of imaging examinations obtained in the ED is also rising, particularly advanced imaging examinations, such as computed tomography (CT). This was confirmed by a study performed at a large academic medical centre reporting a range of 42.3% to 496.6% increase in CT utilization in the ED from 2000 to 2005.

Although documented throughout the CNS, they are the most common intra-axial tumours of the posterior fossa, second only to metastasis. Haemangioblastoma occurs either as a sporadic case or as a component of Von Hippel–Lindau disease (VHL). The peak age of presentation is 40–60 years in sporadic cases and 25–40 years in VHL. Multiple haemangioblastomas are rare in sporadic cases.

Most reports related to cor triatriatum have not considered computed tomography (CT) helpful to diagnose this entity or to evaluate its haemodynamic significance; there is only one case report in the literature in which single-section transaxial CT was used as the initial method to diagnose cor triatriatum in an asymptomatic adult. The role of electrocardiogram (ECG)-gated multidetector CT (MDCT) to diagnose cor triatriatum or to determine therapeutic strategy has not been reported. The development of ECG-gated cardiac MDCT provides outstanding detail of the intra or extracardiac structures with motion-free imaging. The present case report presents a case of cor triatriatum that was diagnosed using ECG-gated MDCT, in which the evaluation of the...

Myxoma is the commonest benign primary tumour and sarcomas account for the majority of malignant lesions. Clinical manifestations are diverse, non-specific, and governed by the location, size, and aggressiveness. Imaging plays a central role in their evaluation, and familiarity with characteristic features is essential to generate a meaningful differential diagnosis. Cardiac magnetic resonance imaging (MRI) has become the reference technique for evaluation of a suspected cardiac mass. Computed tomography (CT) provides complementary information and, with the advent of electrocardiographic gating, has become a powerful tool in its own right for cardiac morphological assessment.

This defect in the semicircular canals, which is attributed to various causes such as erosion of the bone, trauma, or congenital absence, is thought to cause a third mobile window effect in the closed system. This is thought to disrupt the flow of endolymph resulting in clinical presentations such as vertigo and/or oscillopsia, especially if evoked by a loud noise (Tullio's phenomenon). Pressure-induced nystagmus can also be evoked by Valsalva manoeuvres and, less commonly, with tragal pressure.

Frozen section is accurate for distinguishing benign from malignant lesions, testicular function is usually preserved, and there is no evidence that oncological safety is impaired. Such testis-preserving surgery is a rewarding ground for collaboration between urologists, radiologists, and pathologists.

An unexpected radiological abnormality outside the screening programme's anatomical area of interest can occasionally lead to serendipitous early diagnosis of significant disease. It can also lead to a series of arguably unnecessary further investigations, anxiety, and morbidity. However, with any screening programme the role of the responsible clinician is clear and there is usually no doubt who will take responsibility for managing the consequences of any IF. The same can not be said for radiological IF that occur within research studies.

CT also provides important information regarding invasion of the chest wall and surrounding structures. A spectrum of tumours can affect the pleura of which metastatic adenocarcinoma is the commonest cause of malignant pleural disease, while malignant mesothelioma is the most common primary pleural tumour. Certain CT features help differentiate benign from malignant processes. This pictorial review highlights the salient CT appearances of a range of tumours that may affect the pleura.

When it does, there are important considerations and challenges for the radiologist. The physiological changes of pregnancy may mask signs and symptoms of malignancy leading to delayed presentation. Endocrine and physiological changes during pregnancy can interact with tumour biology to alter the behaviour and patterns of growth of certain tumours. The timing and choice of imaging technique pose potential risks to the foetus, but this must be weighed against the risks to both mother and foetus of inadequate investigation or misdiagnosis. This review outlines the general principles and approach to imaging the pregnant patient with suspected malignancy, following which there is a more detailed discussion of the effects of pregnancy on tumour bi...

With increasing weight gain, fat is deposited in a variety of compartments, such as the subcutaneous and visceral regions, as well at various sites in the body. The quantification of fat distribution at different sites proved difficult until the advent of modern cross-sectional radiological imaging techniques introduced from the 1970s onwards.
