A 54 year-old female case of portal vein aneurysm was reported. The aneurysm was located in the right lobe of the liver and its shape was fist-like. Abdominal ultrasonography revealed an anechoic area in the right anterior portion of the liver. The low density area in the right lobe, which was observed in a plain CT scanning, was enhanced remarkably by bolus injection of amidotrizoic acid, and the shape of the lesion was fist-like, consisted of several semiround structures of isodensity. The densities of the lesion and the portal vein changed concomitantly after bolus injection of the contrast reagent. The portal phases of the celiac and the superior mesenteric arteriograms confirmed the lesion to be the portal vein aneurysm directly originated from the right portal vein. Laparoscopy revealed no cirrhotic change of the liver. No sign of portal hypertention was observed. This is the first report of the fist-like shape of the portal vein aneurysm.
