international units (IU) of IFNα, 3 days a week for a total of 24 weeks. After the IFN therapy, the patient demonstrated a normal serum ALT level, and was continuously negative for HCV-RNA, and histology improved from chronic active hepatitis to chronic persistent hepatitis. Follow-up studies with ultrasonography (US) every 3 months and computed tomography(More)
AIM To compare the imaging results with histology and to evaluate the diagnostic sensitivity of imaging modalities for hepatocellular carcinoma (HCC) smaller than 2 cm. METHODS Nodules smaller than 2 cm (n = 34) revealed by ultrasonography (US) in 29 patients with liver cirrhosis were analyzed. Histological diagnosis of HCC was performed by(More)
Spontaneously regressed lung metastasis of hepatocellular carcinoma (HCC) in a 82-year-old Japanese man with liver cirrhosis was recorded. Multiple nodular lesions of both lungs, up to 1 cm across, were shown on chest X-ray when the clinical diagnosis of HCC was made because of the presence of a liver mass on abdominal computed tomography (CT) scan and high(More)
Acute pancreatitis, an uncommon side effect of pegylated interferon α (PEG-IFN α) and ribavirin (RBV) combination therapy, has rarely been reported in the English language literature. Here, acute pancreatitis associated with PEG-IFN plus RBV treatment is described in three patients with chronic hepatitis C, genotype 1b with high serum hepatitis C virus RNA(More)
We describe a 15-mm scirrhous hepatocellular carcinoma (HCC) in a 60-year-old man with B-type cirrhosis. Ultrasound disclosed a 15-mm hypoechoic nodule in segment 7. Contrast-enhanced US revealed heterogeneous, not diffuse, hypervascularity in the early phase and a defect in the Kupffer phase. Contrast-enhanced computed tomography (CT) revealed a(More)
OBJECTIVES AND METHODS Findings of histological analyses of 2 cases of liver biopsy revealing hypovascular nodules are described. RESULTS Ultrasound examination revealed hypovascular and hypoechoic nodules (8 mm in diameter) in segment 1 (case 1) and (8 mm) in segment 8 (case 2). The nodules were detected by only Gd-EOB-DTPA-enhanced MRI. Hematoxylin and(More)
Mucinous cystadenoma with malignant transformation occupying the lower half portion of the right renal pelvis in a 69-year-old Japanese man was recorded. The patient had recent dysuria but no clinical history of pyelonephritis or urolithiasis. Under the clinical diagnosis of unusual renal cyst, the right total nephrectomy was performed. Grossly, the cystic(More)
A case of hypervascular nodules in the liver, but without hepatitis B or C virus infection in a 38-year-old woman with a history of alcohol abuse is presented. An ultrasound disclosed 1-2-cm hypoechoic tumors in the right and left lobes. Magnetic resonance imaging showed high-intensity tumors at both the T1-weighted and T2-weighted sequences. Incremental(More)
We describe a case of takotsubo cardiomyopathy with ventricular fibrillation after gastroenterological endoscopy in a 66-year-old woman. Ten minutes after the upper and lower gastrointestinal endoscopic examinations, the patient lost consciousness, went into respiratory arrest, and became cyanotic; an electrocardiogram (ECG) showed ventricular fibrillation.(More)
Two cases of primary sclerosing cholangitis with hepatic C virus infection in a 62-year-old man and a 60-year-old woman are presented. The infection in the man was eradicated with interferon therapy in 1992. Seven years thereafter, endoscopic retrograde cholangiography revealed a diffuse 2.5-cm-long stenotic lesion in the common bile duct which was(More)
