We report a rare case of peritonitis caused by perforation of an ileal diverticulum. A 56–year–old male patient was admitted to our hospital with fever of sudden onset and abdominal pain. Localized tenderness in the lower right abdomen prompted an abdominal computed tomography, which revealed an increase in the concentration of fatty tissue around the ileocecal region and a diverticulum each in the ascending colon and terminal ileum. We diagnosed localized peritonitis caused by perforation of the ileal diverticulum or ascending colon diverticulum. Conservative treatment was initiated. On day 6, as the patient’s condition deteriorated, surgery was performed. Abscess formation with localized inflammation was observed in the ileocecal region. An ileocecal resection was performed. Histopathological examination of the resected specimen revealed perforation of the diverticulum near the terminal ileum. The postoperative course was uneventful, and the patient was discharged on day 10 after the operation.
