Angiolipoma: A Rare Cause of Colonic Intususception

Introduction: Intussusception in adult is an uncommon clinical entity. An intussusception involving left sided colon due to a benign tumor such as angiolipoma still more uncommon. Prompt pre-operative diagnosis using imaging technique helps in appropriate surgery. Case report: We present a 60years old patient who presented with features of intestinal obstruction who was evaluated with CECT and found to have multiple lipoma on left colon with diverticuli on right colon. On exploration he was found to have colocolic intusception at descending colon, one of the lipoma being the lead point along with right sided colonic diverticuli. He underwent segmental colectomy with transverse colon-sigmoid end to end anastomosis. Final histopathology was reported as multiple angiolipoma with diverticulosis. Conclusion: Pre-operative imaging techniques are of great value in identifying rarer aetiologies of colonic obstruction such as angiolipoma. Surgery forms the best treatment for those patients with symptomatic angiolipoma of colon.
