Ileocolic intussusception caused by ileal lipoma: A case report.
2020
RATIONALE Adult intussusception is rarely observed, accounting for about 5% of all cases of intussusception. Most ileal lipomas are asymptomatic and do not need any special treatment. Herein, we describe a case with ileocolic intussusception caused by ileal lipoma. PATIENT CONCERNS A 27-year-old woman complaints of intermittent abdominal pain for 10 days. DIAGNOSIS Abdominal computed tomography demonstrated ileocolic intussusception. Colonoscopy revealed a spherical polypoid lesion with surface capillary rising from the lateral wall of the ileum. A diagnosis of ileocolic intussusception was made. INTERVENTIONS The patient underwent primary resection of the intussuscepted intestine after which an end-to-end anastomosis was performed. OUTCOMES Histopathology report confirmed a 4.5 cm × 3.5 cm lipoma in the terminal ileum. The patient was discharged on a postoperative day 9 without complications. LESSONS We describe the difficulties in diagnosis and treatment of this rare cause of intussusception and review the literature on adult intussusceptions. The ileal lipoma is a very rare cause of ileocolic intussusception. Abdominal CT and colonoscopy are important for the diagnosis of intussusception and abdominal lipomas. Surgical resection remains the treatment of choice.
