Hepatic artery aneurysms (HAAs) are considered rare. The great improvement in the diagnosis of vascular diseases and the increasing incidence of atherosclerosis have resulted in a wider recognition of these pathologies. Differently from other splanchnic locations, HAAs have a high risk of rupture so that an aggressive treatment is required. Different therapeutic options are currently available: simple ligation of the artery, aneurysm excision with vascular reconstruction, and transcatheter embolization. We describe the usefulness of transcatheter arterial embolization of an 8 cm hepatic artery aneurysm incidentally found on an abdominal computed tomography (CT) scan in an asymptomatic patient.
