A Case of Adult Invagination due to Lymphangioma of the Cecum

Abstract

A 35-year-old man was admitted to the hospital with a history of intermittent abdominal pain. Laboratory tests revealed slight increases of the white blood cell count and serum CRP. Abdominal computed tomography showed the target sign in the right lower abdomen and an ascending colon tumor, suggestive of intussusception. An ileo-colic intussusception was found at operation, with a tumor of the cecum. Ileocecal resection was performed after repositioning of the intussusceptum by the Hutchison technique. The postoperative course of the patient was uneventful. Histopathological examination of the resected specimen showed a lymphangioma of the cecum. Adult intussusception accounts for approximately 5％-10％ of all intussusceptions. Gastrointestinal lymphangioma is extremely rare, representing less than 0.1％ of all lymphangiomas. We reviewed the data of 33 patients with intussusception caused by intestinal lymphangioma, including the present patient, with a discussion of the Japanese literature.
