Abstract
A 90-year-old man was admitted to the emergency room with acute right back pain. Immediate computed tomography (CT) scan demonstrated a large retroperitoneal hematoma and the presence of a ruptured 7-cm in diameter right internal iliac artery aneurysm. The patient subsequently developed rapid onset of hemorrhagic shock, which prompted an emergency operation. He made an uneventful recovery and was discharged on the 27th day after surgery without any problems. Isolated internal iliac artery aneurysms are rare but are dangerous and are associated with a high incidence of rupture and operative mortality. Repair of the aneurysms can be challenging, particularly in the face of rupture.
