Colonic lipoma causing colo-colic intussusception

Abstract

A 32-year-old female patient is presenting with severe right upper quadrant abdominal pain and vomiting. On examination, she had tenderness in the epigastrium, apart from this there were no other positive findings on examination. The clinical diagnosis of acute cholecystitis was made. Her routine investigations were noncontributory. Ultrasound scan of the abdomen revealed thickening of the bowel wall in the region of the hepatic flexure. A contrast enhanced computed tomography of the abdomen was suggestive of ileo-colic intussusception with a lipoma as the lead point. Intraoperatively, she had a colo-colic intussusception involving the ascending colon and the right half of the transverse colon. A pedunculated polyp in the region of the hepatic flexure was the lead point and seen to be obstructing the lumen completely. She underwent a right hemi colectomy with an ileo-transverse anastomosis. Her postoperative recovery was uneventful, and she was discharged on the 5 th postoperative day. The histopathological examination confirmed the polyp to be of the submucouslipomatous variety.
