title: Arteriovenous malformation of the gallbladder.
abstract: Review of the literature shows no reports of vascular malformation of the gallbladder. Herein we report an unusual case of arteriovenous malformation of the gallbladder in a patient with hepatocellular carcinoma. The gallbladder lesion was found incidentally during abdominal angiography for the carcinoma. The angiographic features were specific, comprising dilated and tortuous feeding cystic arteries, a racemose vascular network, and early-filling cystic veins.
