Abstract
A 72-year-old woman came to our hospital with complaints of lumbago and right thigh pain. Blood examination showed white blood cell count of 19000/mm3 and C-reactive protein level of 31.92mg/dl. Abdominal CT scan showed free air in the abdominal cavity and a retroperitoneal abscess. Generalized peritonitis due to intestinal perforation was diagnosed and an emergent operation was performed. Intraoperatively we confirmed the ileal perforation associated with an abscess extending along the psoas muscle. Pathological examination revealed fistulae on the ileal mucosa of ileal diverticulitis. These fistulae connected to the abscess cavity.
Most cases of ileal diverticulm are asymptomatic, but this condition can be complicated by diverculitis, hemorrhage and perforation. The clinical and pathological features of this rare case are briefly reviewed.
