Acute intussusception on a lipoma of the left colon: report of a case

Introduction: Lipomas of the colon are rare benign tumors. Colo-colonic intussusception caused by colonic lipoma is more rare. Case report: We report a case of a 52-year-old patient presenting with recurrent colonic obstruction which occurred in recent days. Colonoscopy revealed a large submucosal mass having benign appearance. Abdominal computed tomography scan diagnosed colo-colonic intussusception due to a large lipoma of the sigmoid colon. Diagnosis was confirmed during operative reduction and resection. He had segmental left colectomy. The postoperative course was uneventful. Conclusion: Computed tomography scan and colonoscopy seem important for diagnosing both lipoma and intussusception. The treatment may be surgical or endoscopic.
