Colonic intussusception by a giant colon lipoma: A case report

Introduction Colonic lipomas are extremely rare, and they can mimic clinical manifestations of a colonic carcinoma, presenting with bowel obstruction or intussusception. We present a case of a 57-year-old female with a colonic lipoma causing a colonic intussusception. A review of the literature is also included. Presentation of case A 57-year-old female patient arrived to the emergency department with bowel obstruction. Imaging studies revealed intussusception triggered by a colonic pediculate lipoma. A left colectomy was performed and the patient had an uneventful recovery. Discussion Two-thirds of colonic intussusceptions are associated with malingnant tumors. There are several therapeutic interventions for the treatment of this disease, which include a segmental colectomy, local excision and even endoscopic removal. Colonic lipomas are extremely rare, and they can mimic a malignant tumor, so it is imperative for the surgeon to rule out a malignancy in order to opt for a more conservative or minimal approach. Conclusion If the diagnosis of a benign disease is uncertain in patients presenting with colonic intussusception, then it should be managed as a malignant lesion due to the higher incidence of large bowel adenocarcinomas presenting with this disease. © 2017 The Authors
