Abstract
A 73-year-old man visited our department with a chief complaint of abdominal pain. Tenderness and muscular guarding were observed in the right lower quadrant. Abdominal ultrasonography showed target signs in the right lower abdomen, and abdominal contrast-enhanced computed tomography showed intussusception led by the cecum. Emergency surgery was therefore performed. Upon laparotomy, the cecum was seen to have folded into the ascending colon, producing an intussusception. The invagination was released using Hutchinson's maneuver, but impaired blood flow was observed in the intestines, and a tumor lesion was palpable in the cecum, so cecal cancer was suspected and ileocecal resection (D3 dissection) was performed. The resected specimen showed a circular, clearly defined, elevated lesion (diameter, about 3 cm) in the cecum. Pathological examination identified lymphangioma. Lymphangioma is a benign tumor that frequently affects the head and neck or axilla in childhood, and finding this entity in the abdominal cavity is rare. Large intestine intussusception in an adult is also relatively uncommonly caused by a benign tumor, and that caused by lymphangioma is extremely rare. We encountered and report herein on a case of cecal lymphangioma that developed intussusception and for which ileocecal resection was performed.
