A 27-year-old man admitted for intestinal obstruction and abdominal pain was found in computed tomography (CT) to have a heterogenous tumor 10 cm in diameter tumor in the pelvis. Magnetic resonance imaging (MRI) showed compression of the urinary bladder and rectum by the tumor. A barium meal study of the small intestine revealed external compression of the ileum but no elevated lesion in the ileal lumen. Angiography of the superior mesenteric artery showed compression of the ileal branch, but no pooling or tumor stain. The tumor was thought to be of the mesenteric organ of the ileum, so we resected the 12×10 cm tumor in the mesentery partially involving the ileum. The tumor, 180 cm proximal to the end of the ileum, was elastically soft with an iregular surface of cystic lesions filled with coagulated blood. The pathological diagnosis was cavernous hemangioma. To our knowledge, only 21 cases of mesenteric hemangioma have been reported in Japan, including our case. Mesenteric hemangioma is thought to be extremely rare.
