A Case of Lymphangioma Arising From the Lumen of the Small Intestine Discovered by Ileocolic Intussusception

Abstract

An 11-year-old girl was admitted to our hospital with severe abdominal pain after suffering from enteritis. Abdominal ultrasonography revealed a target sign, and contrast-enhanced CT revealed an ileocolic intussusception. She underwent laparoscopic surgery at first, but we transitioned to open surgery owing to difficulty in reduction, and the ileum with a tumor was resected. The postoperative course was uneventful and she was discharged on postoperative day 9. The pathological diagnosis was lymphangioma. Generally, the age of onset of intussusception ranges from 6 months to less than 3 years. If the intussusception occurs at an older age, in many cases, the intussusception is caused by an organic lesion such as Meckel’s diverticula and neoplastic lesions. There are few reports on lymphangioma as the cause of intussusception. Since our present case of lymphangioma arose from the lumen of the small intestine discovered by ileocolic intussusception, we report this case on the basis of previous cases.
