Retroperitoneal leiomyosarcoma. Its MR manifestations.
The magnetic resonance manifestations of retroperitoneal leiomyosarcomas in two patients are described. The tumors were isointense to muscle on T1-weighted images and exhibited a relatively high signal on T2-weighted images. Postcontrast T1-weighted images after the administration of gadolinium-dietilenetriaminepentaacetic acid produced moderate enhancement except in regions of central necrosis.
