Liver abscess concomitant with hemobilia due to rupture of hepatic artery aneurysm: a case report.

Hepatic artery aneurysm is an uncommon lesion, usually extrahepatic and rarely intrahepatic. Rupture of hepatic artery aneurysm into the biliary tract is a rare cause of hemobilia. Angiography is the diagnostic method of choice and surgical intervention is the procedure of choice for extrahepatic rupture. Interventional angiography with embolization is optimal for inaccessible intrahepatic aneurysm and extremely poor risk patients. Reported here is a rare case of left intrahepatic artery aneurysm ruptured into the intrahepatic bile duct in the course of liver abscess. Embolization of the hepatic artery resulted in cessation of bleeding.
