Absence of the terminal portion of the portal vein and its intrahepatic branches was demonstrated in a 22-year-old woman with focal nodular hyperplasia (FNH) of the liver. Various imaging studies and angiography showed that the portal vein entered into the inferior vena cava just above the renal veins. The clinical and radiological features of this patient(More)
Intra-abdominal hemorrhage caused by omental artery rupture is a rare condition. There are few reports on the treatment of omental artery rupture with only transcatheter arterial embolization (TAE). A 27-year-old man presented to our emergency room with upper abdominal pain that suddenly occurred during sleep. Abdominal computed tomography (CT) revealed(More)
We present a case of a 69-year-old man with primary hepatic carcinosarcoma who underwent computed tomography that revealed a hypervascular hepatic tumor with local dense calcification. Gadolinium-ethoxybenzyl-diethylenetriamine pentaacetic acid (Gd-EOB-DTPA)-enhanced magnetic resonance imaging revealed hyperintense lesions in the hepatobiliary phase that(More)
Development of abdominal calcifications due to pseudomyxoma peritonei is rare. The authors present three cases whereby computed tomographic (CT) studies during or after chemotherapy for pseudomyxoma peritonei demonstrated development and progression of punctate calcifications in the abdomen. The clinical and CT findings of these cases are presented together(More)
A 73-year-old man underwent laparoscopy-assisted partial resection of the rectum to treat rectal cancer diagnosed in September 2011 at a previous hospital. Lymph node dissection was not performed and the vertical margin was positive. When multiple liver tumors were detected 10 months later, the patient was referred to our hospital. A computed tomography(More)
A 67-year-old man with elevated hepatobiliary enzymes was referred to our hospital for further examination. Computed tomography indicated hilar cholangiocarcinoma of Bismuth type Ⅳ and revealed invasion of the right hepatic artery and the left portal vein. We diagnosed locally advanced unresectable hilar cholangiocarcinoma, and performed 5 courses of(More)
A 45-year-old woman, who had had rheumatoid arthritis for 12 years, had three attacks of cerebral embolism over two months and died after the final attack. Intensive clinical laboratory investigations did not disclose any specific origins of emboli, but an autopsy revealed a nodule at the base of the aortic valve which was pathologically proved to be a(More)
In the treatment of hepatocellular carcinoma, atypical, off guideline multidisciplinary approaches are sometimes effective. A 70-year-old man was diagnosed with multiple hepatocellular carcinomas, multiple bone metastases, and a right adrenal metastasis. Sunitinib was started and the primary hepatic lesions and bone metastases disappeared. However, his(More)
