Hemobilia is usually attributed to hepatic trauma. However, hepatic tumor was reported to be associated with only 5% of hemobilia, and only 1% of all hemobilia is reported to be caused by gallbladder carcinoma. We present a case of hemobilia in a patient with gallbladder carcinoma that was successfully controlled by angiographic procedures. A 64-year-old woman was admitted due to jaundice and dizziness. Duodenoscopy revealed blood clots at the ampulla of Vater. Endoscopic retrograde cholangiography showed amorphous filling defects within the lumen of a dilated common bile duct. On selective angiography, mild tumor staining and cystic arterial bleeding were found, and thus transcatheter arterial embolization was performed with a steel coil and gelform for control of the bleeding.
