Idiopathic cystic artery aneurysm complicated with hemobilia and acute pancreatitis.

Background: Aneurysm of the cystic artery is not common, and it is a rare cause of hemobilia. Most of reported cases are pseudoaneurysms resulting from either an inflammatory process in the abdomen or abdominal trauma.

Methods: We report a healthy individual who developed hemobilia and acute pancreatitis associated with cystic artery aneurysm.

Results: The patient was managed with angio-embolization with an uneventful post-embolization course.

Conclusions: Visceral artery aneurysms are rare and can rupture with potentially grave outcome due to excessive bleeding. Angiographic embolization as a common method of treatment for visceral artery aneurysms was used in our patient with good outcome.
