Pseudoaneurysm in a chronic pancreatitis patient: report of a case, with emphasis on contrast-enhanced sonogramsEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Abstract The association between pseudoaneurysm of the splenic artery and pancreatitis is now established. 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 comp...

High-intensity focused ultrasound induced apoptosis with caspase 3, 8, and 9/6 activation in rat hepatomaEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Conclusion HIFU-induced apoptosis in vivo and in vitro is one of the mechanisms for tumor control and is mediated by caspase 3, 8, and 9/6. The significantly greater activation of caspase 8 than of caspase 9/6 suggests that the apoptosis pathway induced by HIFU might be more mitochondria dependent than death receptor dependent. However, further examination will be needed.

Morphological and functional evaluation of normal and abnormal fetal growth by ultrasonographyEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Abstract Correction or estimation of gestational age is essential for the evaluation of fetal growth. 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 circ...

Portal gas in a diabetic patient under pharmacotherapy with an alpha-glucosidase inhibitor: report of a case with emphasis on US findingsEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
We report the case of a 56-year-old diabetic man under pharmacotherapy with an alpha-glucosidase inhibitor in which portal gas was incidentally detected by ultrasound (US). 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 conc...

Abstract A 7-year-old female infant presented with an asymptomatic soft tissue mass in the right neck. 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.

A case of dermoid cyst of the floor of the mouth: ultrasonography was more useful than computed tomography and magnetic resonance imaging in the preoperative diagnosisEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
This report presents a case of dermoid cyst (dermoid type) of the floor of the mouth in a 21-year-old man. 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 l...

Glycogen-rich clear cell carcinoma of the breast: a case reportEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Abstract Glycogen-rich clear cell carcinoma (GRCC) of the breast is a rare malignant breast tumor. 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 s...

Primary small-cell carcinoma of the breast: a case reportEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
We report a case of small-cell carcinoma of the breast. 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 ...

Three-dimensional sonographic features of a fetus with Wolf-Hirschhorn syndromeEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
We present a case of fetal Wolf-Hirschhorn syndrome diagnosed by conventional two-dimensional and three-dimensional ultrasonography. 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-Hirsc...

Multiple anechoic hepatic nodules in a patient with malignant lymphoma: report of a case with an emphasis on B-mode sonogramsEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
We present a case of hepatic malignant lymphoma (ML) in which the hepatic ML nodules were imaged as round anechoic nodules with posterior echo enhancement, mimicking hepatic cysts on B-mode ultrasonography (US). 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. C...
