Ileo-Ileal Intussusception Secondary to Ileal Lymphangioma

Abstract

A 6-year-old girl was brought to our hospital owing to intermittent abdominal pain that started 3 hours earlier. Abdominal Computed Tomography showed intussusception at the hepatic flexure. A noninvasive reduction was performed. On hospital day 3, the intermittent abdominal pain recurred. Abdominal ultrasonography showed a target sign at the hepatic flexure and a low-echoic lesion in the advanced part of the intussusception. We diagnosed that intussusception had recurred and performed noninvasive reduction again. Thus, we performed an operation. Surgical findings revealed ileoileocolic intussusception. A 23 × 22 × 9 mm raised lesion was found in the ileum. We performed a partial resection of the ileum, followed by end-to-end anastomosis. Histopathological findings revealed an ileal lymphangioma. Her postoperative course observed over six months was uneventful. Ileal lymphangioma is rare in children, but if ultrasonography indicates a low-echoic lesion in the advanced part of the intussusception, it is important to operate as early as possible because lymphangioma or other organic diseases may be present.
