An 80-year-old man presented with a chief complaint of abdominal pain, accompanied by peritoneal irritation over the entire abdomen. Abdominal CT scan showed a high density area in the ventral side of the right kidney and pelvic cavity. Acute intraabdominal hemorrhage was suspected. Laparotomy revealed aneurysms in the right gastroepiploic artery with rupture, which were partially resected. Histopathological examination clearly revealed partial disruption of the tunica media in the right gastroepiploic artery, justifying the diagnosis of segmental arterial mediolysis.
