Hepatic artery aneurysm, an unusual cause of obstructive jaundice: MR cholangiography findings

Hepatic artery aneurysms are rare vascular lesions, often with a nonspecific clinical presentation, and difficult to diagnose before rupture. We report the case of a patient with obstructive jaundice caused by a compression on the right biliary duct by a right hepatic artery aneurysm in which the diagnosis was suggested by magnetic resonance cholangiography and confirmed by Doppler sonography and preoperative digital subtraction angiography.
