Abstract
We report a rare case of leiomyosarcoma of the ileum showing a pedunculated extraluminal development, which was succoesbully diagnosed preoperatively. A 69-year-old man visited his primary physician because of lower abdominal discomfort. Abdominal ultrasonography (US) showed a mass in the lower abdomen and he was transferred to the hospital. From the results of imaging studies, especially abdominal angiography, the patient was diagnosed as having a leiomyosarcoma of the ileum. The tumor, 11×10×8cm in size, showed a pedunculated extraluminal growth from the antimesenteric side of the ileum at 100cm from the Bauhin vulve. The ileum including the tumor was excised by a wedge resection. The diagnosis of leiomyosarcoma of the ileum was made based on the histological findings of the resected tumor. The patient has been in good health without any signs of recurrence, as of 1 year after the operation.
