Hepatic artery aneurysms are a rare condition that can be fatal if rupture happens. Often, they are incidentally identified in routine imaging. Intervention is indicated when symptomatic, if they reach 2cm or more of size, in patients presenting with multiple hepatic artery aneurysms and in all pseudoaneurysms. We describe the case of a 57 year-old female, to whom a post-traumatic hepatic artery aneurysm was diagnosed. Open surgical repair was successfully accomplished.
