title: Paraumbilical vein aneurysm. Case reports.
abstract: Two cases of paraumbilical vein aneurysm are reported. The patients were diagnosed as having cirrhotic liver with portal hypertension. Angiography and contrast-enhanced computed tomography demonstrated a dilated paraumbilical vein arising from the left branch of the portal vein. Furthermore, localized dilatation of a paraumbilical vein was demonstrated. The focal aneurysmal dilatation of the dilatated paraumbilical vein is rare.
