Extraperitoneal pelvic leiomyosarcoma. MR findings in a case.
The magnetic resonance imaging (MRI) of a patient with nongynecologic pelvic leiomyosarcoma is presented. A retroperitoneal mass appeared under the broad ligaments, in the right paravesical and parametrial, lateral pararectal site. The mass leaned on the uterus and vagina. On MRI, the mass had solid structure, isointense on T1-weighted images, inhomogeneously iperintense on T2-weighted images with central areas of increased intensity. Late after contrast agent administration, the mass appeared inhomogeneously ipointense with areas of fair late contrast enhancement. The morphology of the tumor, the retroperitoneal site, and MRI sequences make the differential diagnosis. These evidences were useful in treatment planning.
