On computed tomography scan, a huge cystic lesion about 10 cm in diameter was observed in the pelvic cavity, attached to the vagina and the neck of uterus. Pyometra was strongly suspected; however, a probe could not be inserted into the opening of the uterus because of atrophic changes. Therefore, we decided to perform endoscopic ultrasound (EUS)-guided drainage of the pyometra using the transrectal route. Foul-smelling yellow–brown pus was aspirated. A guide-wire was inserted and a 7 Fr catheter was inserted into the pyometra through an external fistula. We thus completed the treatment of pyometra without surgical resection.

The diagnostic tests included computed tomography, ultrasound, and contrast-enhanced ultrasound. Radical surgical resection was performed and histological examination confirmed a malignant solitary fibrous tumor of the pleura. The novelty of the case is the use of contrast-enhanced ultrasound in the diagnostic workup.

At the time of admission, she had already had a cardio-embolic stroke with loss of recent memory and slight paralysis of the right upper arm. It was difficult to distinguish between thrombus and tumor. However, her clinical condition required surgical resection as soon as possible. We performed cardiac CT to evaluate the coronary arteries and to scan the mass at the left ventricular apex. This CT evaluation revealed another mass at the left atrial appendage. Thus, these two masses were highly suggestive of thrombi. Subemergency surgical resection of the two masses and a part of the myoc...

The patterns of the to-and-fro waveforms were diverse in each of the patients: both hepatopetal and hepatofugal flow occurred in a single waveform in case 1, changes in the flow direction with flow interruption were noted in case 2, and changes in flow direction without observation of flow interruption and changes after meals were noted in cases 3 and 4, respectively. These waveforms may represent a transitional phase during the development of a portal systemic shunt in patients with portal hypertension.

Recent advances in 64-slice multidetector computed tomography (64-MDCT) allow accurate measurement of left atrial appendage (LAA) volume. The aim of this study was to evaluate the accuracy of LAA sizing by TEE in comparison with 64-MDCT in patients with atrial fibrillation. Electrocardiogram-gated 64-MDCT and TEE were performed within 2 days in 18 consecutive patients (63 ± 9 years old, 12 males, 5 paroxysmal atrial fibrillation) with nonvalvular atrial fibrillation. LAA area and LAA volume were measured at end-systole by TEE and 64-MDCT, respectively. The largest LAA area was measured on TEE image. Five patients were in sinus rhythm...

The previous misdiagnosis occurred due to sonographic pitfalls in gray-scale and color imaging, which led the operator to make a false interpretation. Knowledge of Doppler analysis and sonographic interpretation of arterial coiling may improve the diagnostic accuracy for this condition.

We evaluated early response of transcatheter arterial chemoembolization (TACE) for hepatocellular carcinoma (HCC) by quantitative analysis of intratumoral vascularity with CE-US in three patients. Three patients (one man, two women) with HCCs were treated in July 2009. CE-US with perfluorocarbon microbubbles (Sonazoid) and CT were performed serially before and 5 days after TACE. Post-processing enhancement intensity on US was analyzed to determine mean transit time (s), time to peak (s), enhancement peak intensity (dB), and “A” (scaling factor) by ultrasound quantification software after the data were ...

The fetus was diagnosed as TGA and referred to our hospital at 28 weeks’ gestation. cTGA was found at 29 weeks’ gestation in our hospital, and no additional cardiac anomalies were seen prenatally. After birth, patent ductus arteriosus with bidirectional flow was present. Careful examination of the four-chamber view suggested atrioventricular discordance. Identification of a parallel course of the great vessels, with the aorta anterior and to the left of the pulmonary trunk (l-transposition), may help accurate prenatal diagnosis of cTGA.

The umbilical tumor was observed as a hypoechoic mass with punctate hyperechoic foci. A pathological specimen obtained by needle biopsy confirmed adenocarcinoma with psammoma bodies. A comparison of the ultrasonographic findings with the pathological findings of the resected specimen suggested that the hyperechoic foci corresponded to psammoma bodies. When hyperechoic foci are observed inside SMJN by ultrasonography, adenocarcinoma from ovarian cancer should be included in the differential diagnosis.

Left femoral condyle samples from a 6-month-old pig and a 3-year-old pig were used. Radiofrequency signals from the cartilage surface and cartilage–bone interface were acquired using the ultrasound transducer for nine points in each sample. TOF was calculated by three amplitude-related methods (peak amplitude, peak envelope, signal phase) and a cross-correlation method. Cartilage thickness was measured microscopically, and S...

The authors report a case of slipped distal femoral epiphysis during a breech presentation in a twin pregnancy birthing process, diagnosed by ultrasonography. This type of separation could be difficult to detect in the newborn on plain radiographs because of the non-ossification of the epiphysis. Therefore, the use of sonography is helpful to make an early and accurate diagnosis in order to avoid malunion and deformities of the affected limb. Through this case report we will see the diagnostic value of high-resolution ultrasonography in diagnosing newborn injuries of the limbs, and particularly in the diagnosis of radiographically occult epiphyseal separation.

A 58-year-old man was referred to our hospital because of a pancreatic mass found by positron emission tomography (PET) using 18F-fluorodeoxyglucose (FDG) during a medical checkup in 2009. Trans-abdominal ultrasonography revealed a 24-mm hypoechoic mass at the pancreatic tail with calcification inside. Multiphasic computed tomography (CT) showed a solid mass with delayed enhancement. EUS revealed a hypoechoic mass without lateral shadowing, and neither a septum nor cystic component was detected. CE-EUS using Sonazoid® showed a hypovascular mass compared with the surrounding pancreatic parenchyma, and the inside of the mass was e...

A 34-year-old woman was referred to our hospital at 16 weeks’ gestation. Ultrasound examination revealed a left anterolateral fetal neck mass indicating typical findings of a teratoma. The tumor grew to tremendous size until occupying most of the uterine cavity causing severe discomfort for the patient. This necessitated ultrasound-guided removal of the intracystic fluid of the massive cervicofacial teratoma during pregnancy. Fetal MRI clearly demonstrated the mass extending from the orbit to the anterior chest wall without compression or deviation of the fetal airway. The entire mass increased to 18 cm in diameter at 37 weeks’ gestation. Classical ces...

The course of the disease was monitored by ultrasound every 6 months. At each examination, the tumor was found to have increased in size by several millimeters, but the sonographer decided that the increase was within the range of error. After 4 years, the tumor showed a rapid increase in size. With a diagnosis of threatened rupture, the patient’s life was saved by surgical intervention. In this case, the observations were only compared to the findings from the previous examination, and the slight increase in tumor size was considered within the range of error. It is important to compare the findings not only with those from the previous examination but also with earlier r...

His progress was favorable until April 2008, when he was admitted to our hospital with melena. B-mode ultrasonography revealed a 5-mm defect in the abdominal aorta at the graft anastomosis, and an umbilicated lesion was seen projecting between the posterior wall of the third part of the duodenum and the abdominal aorta. A color signal was noticed at this site on color Doppler ultrasonography, leading to the diagnosis of a secondary aortoduodenal fistula (ADF). We resected the inflammatory mass comprising the graft and the third part of the duodenum, and performed prosthetic re-implantation, omentopexy, and duo...

As the depth of the transducer is altered, the leaflet image is gradually skewed in relation to the plane of the prosthetic valve ring. The leaflet-like image consistently overlaps the line that is drawn from the transducer position to the atrial side edge of the leaflet, indicating that this image is caused by reverberations. Three-dimensional TEE shows that the leaflet image is not semilunar but is elongated towards the left ventricle and unusually tilted. As viewed from the ventricular side, the ring image is elongated and forms a cylinder-like image in...

No defect in the ultrasound beams was found in any of the probes, but a significant decrease of the brightness was found after a certain period of use of the linear-type probe. Disinfection with alcohol may degrade ultrasound probes despite its high degree of effectiveness in preventing iatrogenic bacterial transmission.

We encountered a case of suspected peritoneal pregnancy in which we were able to make a definitive diagnosis by ultrasonography of complete uterine rupture in early mid-trimester. The possibly distinctive finding is the high-echo area that extends from the endometrium to the uterine serosa. This contiguous, highly echogenic finding should be recognized as characteristic of complete rupture of the uterus.

Carcinogenetic development of an HCC is a multi-step process, and a differential diagnosis between a dysplastic nodule and a well-differentiated HCC is often difficult. A bright loop appearance is a significant finding that indicates disappearance of fatty deposition in the central area of the nodule during the progression toward HCC, however such a finding is rare in cases of sub-centimeter-sized HCCs. We encountered a case of HCC that developed a bright loop appearance on ultrasound (US) without enlargement approximately 2 years after diagnosis as a dysplastic nodule. Moreover, the hypoechoic area in the cente...

Antepartum hemorrhage at 24 weeks of gestation prompted a close investigation of the uterine cervix, internal os, and placenta. We detected a low-lying bilobed placenta with umbilical cord insertion in the lower uterine segment. Furthermore, one of the connecting vessels of the bilobed placenta passed directly above the internal os. Vasa previa was suspected and confirmed with color Doppler and MRI. The fetus was delivered uneventfully by planned Cesarean section at 38 weeks of gestation. It should be considered that placenta previa (including low-lying placenta), bilobed placenta, and umbilical cord insertion in the lower uterine segment are associated with high risk of vasa previa.

Although a definitive diagnosis can be best made by surgical resection, computed tomography (CT) and magnetic resonance imaging (MRI) can be used as radiological methods to diagnose a pulmonary lymphangioma preoperatively. Endoscopic ultrasonography is a new method for visualizing pathological changes in the mediastum and may be used for preoperative diagnosis of a pulmonary lymphangioma, which is a rare example of a mediastinal disease.

At 33 weeks of gestation, the cyst disappeared. Ultrasonography showed fetal bowel dilatation, polyhydramnios, and intraabdominal calcifications. Fetal meconium peritonitis was diagnosed prenatally. Because the fetal ileus became worse, a cesarean section was performed at 35 weeks of gestation; a female infant weighing 2,131 g with an Apgar score of 8 was delivered. Six hours after birth, the neonate received an ileostomy. The bowel was reanastomosed 42 days after the initial operation. On postoperative pathology, a meconium pseudocyst was diagnosed.

Statistical echo characteristics changed with the density of the heterogeneous scatterer buried in a speckle. Results  The new analysis method for a medium in which some tissues are embedded was proposed in consideration of analysis results from computer simulations. In the new method, it is possible to eliminate the influence of a cyst or veins and to detect the existence of fibers more clearly than in previous methods.

Currently, the only licensed contrast agent is SonoVue, a sulfur hexafluoride-filled microbubble contrast agent. In combination with a low mechanical index contrast-specific imaging mode, SonoVue-enhanced CEUS can be used to visualize the micro and macro-vasculature continuously. Since 2004, CEUS has been widely used in China in various clinical scenarios. The authors compared CEUS with baseline ultrasound or contrast-enhanced computed tomography with regard to characterization of focal liver lesions (FLLs). On CEUS, heterogeneous or homogeneous hyperenhancement during the arterial phase and washout in the portal/late phase are typical findings for hepatocellular c...

A 59-year-old man with chronic hepatitis C was admitted to our hospital. CEUS clearly showed the thread and streaks sign in a solid lesion that occupied the right main branch of the portal vein. HAIC was performed, and CEUS after HAIC clearly showed disappearance of the thread and streaks sign. CEUS was very useful in diagnosing PVTT and in evaluating the effectiveness of HAIC in this case.

During RFA, B-mode ultrasonography showed a swirling high echoic lesion in the artificial pleural effusion. A real-time scan performed using contrast-enhanced ultrasonography (CEUS) revealed a jet-like extravasation of contrast medium and pooling of microbubbles in the pleural cavity, which were confirmed by angiography. CEUS successfully identified the site of bleeding and can be regarded an effective tool for detecting active bleeding in an emergency.

Rupture of an aneurysm is a lethal condition, and early diagnosis and treatment are required to prevent this hazardous life-threatening complication. In our case, early detection of pseudoaneurysm of the splenic artery enabled us to start prompt embolization, which yielded good results. Splenic infarction is known to be an important and frequent complication of transarterial embolization of splenic artery aneurysms. Thus, when performing transarterial embolization of a splenic artery aneurysm, this complication must be kept in mind and it is absolutely necessary to confirm the presence or absence of this complication after embolization of the aneurysm. In our case of ...

The tumor was resected with the right lobe of the thyroid and the first tracheal ring, which revealed a PA impacted within the thyroid. PAs originating outside of the salivary glands are rare, and there have been no reports of PAs arising from the lateral side of the trachea. This report describes the first reported, and unique, case of this type of tumor.

The lesion showed a heterogeneous internal structure, composed irregularly of hyperechoic and hypoechoic areas, and it also showed weak posterior echo enhancement. Contrast-enhanced US showed the so-called fill-in pattern, leading to the diagnosis of hepatic hemangioma. The patient’s abdomen showed no other abnormal findings, which stressed the relationship between the hemangioma and the patient’s symptoms. When the diagnosis of hepatic hemangioma is conclusive, surgical therapy is indicated only in patients with severe symptoms. Our patient was considered to be a candidate for enucleation of the lesion. Histopathologically, the lesion included no areas of hemorrhage or nec...

Transthoracic and transesophageal echocardiographic studies revealed tunnel-type subaortic stenosis with aortic valvular stenosis, for which she underwent aortic valve replacement and myomectomy of left ventricular outflow tract. Progression of subaortic stenosis should be considered in patients with only mild aortic valve stenosis after previous cardiovascular surgery. Echocardiography contributed significantly to making the diagnosis and therapeutic decision in our patient. Content Type Journal ArticleCategory Case ReportDOI 10.1007...

When necessary, an appropriate fetal biometric parameter should be selected depending on fetal size. In the first trimester, crown–rump length (CRL) is appropriate, especially when the CRL is 20–40 mm. In the second trimester, biparietal diameter (BPD), head circumference (HC), and femur length (FL) are of equal predictability. Fetal weight estimation is still the basis of evaluation of fetal growth. The most predictable formula currently available includes the parameters BPD (or HC), abdominal circumference (AC), and FL. Serial measurements of AC are useful for diagnosis of intrauterine growth restriction (IUGR) and macrosomia. Quantitative evaluation of soft tis...

In this case, detection of gas echoes in the gallbladder wall and the surrounding hepatic tissue led us to an appropriate treatment. US is now the technique of first choice for diagnosing gallbladder diseases, and knowledge of US findings encountered in this case can help prevent a hazardous delay in emergent treatment.

It showed multiple echo spots moving in the portal vein. Doppler signals confirmed them to be bidirectional and spiky, which immediately led to the diagnosis of portal gas. A change in oral antidiabetic drug caused the portal gas to disappear. We stress the usefulness of US and Doppler US for detecting and diagnosing portal gas. Although detailed analysis of a larger series of diabetic patients under this therapy is needed to draw a definitive conclusion, our observation merits attention. We also briefly review the literature. Content Type Journal ArticleCategory Case ReportDOI 10.1007/s10396-009-0221-7Authors ...

The tumor was considered to be a benign one because it had a smooth margin and no change in its size was observed. Ultrasonography showed a 4.5-cm-diameter solid tumor with a smooth, well-defined border. Inside the tumor, flow signals were observed on color Doppler and there were numerous echogenic spots. Magnetic resonance imaging (MRI) examination showed findings consistent with an ectopic thymus, i.e., T1- and T2-weighted images showed thymus-like signals. The course of the case is being continuously followed.

It uses a combination of speckle tracking and complex geometric analysis, allowing tracing of myocardial activity throughout the cardiac cycle. In this case, evaluation of the myocardial dynamics in the fetus by VVI was started at 27 weeks of gestation, and both the systolic and diastolic velocities and the ejection fraction in the aneurysmal segment were less than in the other segments. VVI imaging at 35 weeks of gestation showed this difference even ...

The preliminary preoperative assessment was made by using three modalities: computed tomography (CT), magnetic resonance imaging (MRI), and ultrasonography (US). CT depicted the lesion as a well-circumscribed, unilocular, homogeneous low-density mass. MRI showed a mass lesion located in the submental region between the geniohyoid and mylohyoid muscles. The lesion exhibited homogeneous intermediate signal intensity on T1-weighted images and homogeneous high signal intensity on T2-weighted images. The wall of the lesion was well enhanced on gadolinium-enhanced MRI. CT and MRI could not demonstrate any fatty components within the lesion and only indicated that the lesion was cystic...

We recently encountered a case of GRCC and report our imaging findings here. The patient was a 49-year-old woman with a mass in her right breast. Mammographic study showed no definite mass shadow because the breast was dense. No calcifications were identified. Ultrasonography disclosed a hypoechoic mass that had a diameter of 1.3 cm, partially irregular borders, heterogeneous internal echoes, and posterior acoustic enhancement, suggesting an invasive carcinoma. Histologic study of core needle biopsy specimens showed a solid proliferation of large clear carcinoma cells, suggestive of a ductal carcinoma. The carcinoma cells possessed clear cytoplasm larger than that typical of ...

The patient was a 54-year-old Japanese woman with a left breast mass. Mammography revealed a 1.2-cm microlobulated mass with partially ill-defined borders. Ultrasonography disclosed a hypoechoic mass measuring 1.8 × 1.2 × 1.2 cm with heterogeneous internal echoes and partially ill-defined borders. The shape of the mass was round and taller than it was wide in the orthogonal section to the longest axis of the mass. These imaging findings suggested a malignant tumor. Fine-needle aspiration cytology of the tumor also suggested a ductal carcinoma. Breast-conserving surgery was performed with axillary sentinel lymph node biopsy. A diagnosis of small-cell carcinoma of the breast was made based on the histologic and immunohistochemic...

Conventional two-dimensional ultrasonography revealed a diaphragmatic hernia, nuchal edema, and suspected hypospadias. Three-dimensional ultrasonography clearly showed a flattening of the face, a high forehead, a broad nasal bridge continuing to the forehead, exophthalmos, and micrognathia (resembling the appearance of a Greek warrior helmet), but conventional two-dimensional ultrasonography did not depict these findings. Prenatal chromosomal analysis confirmed the diagnosis of Wolf-Hirschhorn syndrome [46XY, del(4)(p15.2)]. Here we demonstrate how three-dimensional ultrasonography provided a novel visual depiction of the facial dysmorphism, which helpe...

However, the boundary echo between the nodules and the surrounding hepatic tissue seemed to be less distinct than that of a hepatic cyst. Contrast-enhanced US showed the nodules to be hypervascular, which ruled out the possibility of hepatic cysts. Our observation stresses the importance of boundary echo for the diagnosis of hepatic ML on B-mode US. We also offer a possible explanation for this phenomenon.

In this second and final part of the review, we will focus on and discuss various aspects of low-intensity US, with emphasis on the biomolecular effects, US-mediated gene transfection (sonotransfection), and US-mediated permeabilization (sonopermeabilization). Sonotransfection of different cell lines in vitro and target tissues in vivo have been reported. Optimization experiments have been done and different mechanisms investigated. It has also been found that several genes can be up-regulated or down-regulated by sonication. As to the potential therapeutic applications, systemic or local sonotransfection might also be a safe and effective gene therapy method in...

Mild thermal effects of US have been commonly applied to physical therapy. Though US has clear beneficial effects, the advantage of using US over other heating modalities remains unclear. US has also been used in vivo and clinically in the treatment of wounds and fractures, with promising results. On the biomolecular level, studies have shown that US can induce apoptosis and that certain conditions can provide optimal apoptosis induction. As to potential therapeutic applications, in addition to the thermal and other physical effects, apoptosis induction by US may off...

The patient was a 32-year-old woman with dual ectopic thyroid accompanied by positive antithyroid antibodies. The simultaneous occurrence of dual ectopic thyroid and positive antithyroid antibodies has been documented in only two cases: the case discussed here and one previous case. The cervical ectopic thyroid was followed up by ultrasound, which showed an increase in the size of the lesion and an internal echo texture that became slightly heterogeneous after the patient had her second child. We speculated that these changes resulted from the changes in hormone demand brought on by pregnancy and parturition. Content Type Journal ArticleCateg...

Chest X-ray revealed massive pleural effusion on the left side. Contrast-enhanced ultrasonography using Levovist was performed to confirm the transdiaphragmatic passage of ascitic fluid into the pleural cavity. After injection of Levovist into the peritoneal cavity, an enhanced pulsative flow into the pleural cavity was detected. This is the first report of hepatic hydrothorax diagnosed by contrast-enhanced ultrasonography. This method is safe and useful for the diagnosis of hepatic hydrothorax, and it allows observation of the real-time movement of ascitic fluid from the peritoneal cavity to the pleural space and detection of the site of the peritoneopleural communication.

The patient was a 75-year-old man who had been diagnosed as having a simple hepatic cyst at our hospital and had been followed up by abdominal sonography (US) for about 10 years. However, the lesion subsequently showed a sudden increase in size and a marked change in US findings, i.e., from a benign hepatic cyst to a complete solid lesion. Contrast-enhanced US revealed the lesion to be filled with fine vessels. This rapid change led us to strongly suspect a hepatobiliary cystadenocarcinoma and, thus, left lateral segmentectomy was performed. The patient is doing well 6 months after the surgical treatment.
