MR imaging of gastrointestinal leiomyosarcoma.
Two cases of leiomyosarcoma, one in the esophagus and the other in the small intestine, underwent magnetic resonance imaging (MRI). Spin echo T1-weighted images of both leiomyosarcomas showed almost the same intensity as muscle. Spin echo T2-weighted images showed the tumors to be hyperintense compared with fat; however, the esophageal tumor was more hyperintense than the small intestinal one. The jejunal leiomyosarcoma had a central cavity on MRI and CT, suggesting that it was malignant.
