Ileocolic intussusception caused by ileal lipoma

Abstract

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.

Jejunal intussusception due to an atypical lipomatous tumor: a rare case report

“…Intussusception in adulthood is unusual, with an incidence of ~2–3 cases per 1 000 000 individuals per year [ 4 ]. Although childhood intussusception is idiopathic in 90% of cases, a mechanical motive and, more specifically, neoplasms are the most frequent cause of adult intussusception [ 8 ]. The site of the intussusception is associated with the possibility of malignancy, with colo-colonic intussusception reported having neoplasia as the lead point in 69% of cases and malignancy in 70% [ 9 ].…”
