Gastrointestinal Image: A True Giant Transverse Colon Diverticulum

ABSTRACT: Giant colonic diverticulum is an extremely rare condition in colonic diverticular disease. More than 90% of giant colonic diverticula are found in the sigmoid colon. Inflammatory and pseudodiverticula are the most frequent. Only one case of a true diverticulum of the transverse colon has been reported in the literature. CASE REPORT: We report a case of a 22-year-old woman presenting with constipation and meteorism from childhood. A plain abdominal X-ray showed a round radiolucent air-filled cyst. Barium enema revealed a single, large diverticulum of the transverse colon. An extended right hemicolectomy with primary end-to-end anastomosis was performed. The postoperative course was uneventful, and she was discharged in 1 week without any complications. Histopathology showed a true diverticulum containing all layers of the colon.
