Hemobilia in a patient with multiple hepatic artery aneurysms: a case report and review of the literature.

Hepatic artery aneurysm is a rare vascular lesion that accounts for nearly 10% of hemobilia cases. Its etiology is most often atherosclerosis, trauma, or infection. Autoaggressive disorders are rarely associated with hepatic artery aneurysm as is thyroid dysfunction. Presented here is a case of hemobilia secondary to a rupture of one of multiple aneurysms of both right and left hepatic arteries in a women with a history of rheumatoid arthritis, hypothyroidism, and hypertension. Surgical intervention has been the rule in the past. Selective transcatheter embolization has gained clinical application in recent years, especially in the treatment of intrahepatic aneurysms. Its efficacy and safety are demonstrated by this case.
