Computed tomography during arterial portography in idiopathic portal hypertension.

Computed tomography (CT) during arterial portography was performed in two cases of idiopathic portal hypertension (IPH). Multiple patchy low-density areas with unclear margins and abnormally short distances between some of the medium-sized portal branches and the liver surface were demonstrated. These findings were distinctly different from those of liver cirrhosis. CT during arterial portography was useful for differentiating IPH from liver cirrhosis.

Right perirenal biloma due to a common bile duct stone: CT demonstration.

Most reported extrahepatic bilomas have been located around the liver, especially in the intraperitoneal cavity. A case of a right perirenal biloma due to a common bile duct stone is presented. Intraoperative cholangiography revealed extravasation of bile from the branch in the caudate lobe. CT accurately demonstrated the fluid around the inferior vena cava and in the right perirenal space, which indicated continuity of the liver and right perirenal space.

Hepatic granuloma with progressive calcification: CT appearance.

Calcification in the liver is uncommon but not rare in clinical practice, and may be caused by many pathological conditions. We report a patient with hepatic mass on abdominal sonogram and CT scan. The mass was shown as a hypoechoic lesion on abdominal sonogram and as a well-marginated hypodense mass on pre- and postcontrast CT. Inflammatory granuloma was diagnosed by pathological examination following percutaneous needle biopsy. A follow-up precontrast CT scan was performed 22 months after the initial examination, and the hepatic granuloma could be the cause of hepatic parenchymal calcification.
