Abstract:
A case of ossified leiomyoma of the deep soft tissues of the left thigh is presented. The radiographic appearance suggested
a low-grade chondrosarcoma. MRI of the lesion showed signal characteristics similar to muscle on both T1- and T2-weighted
spin echo sequences with linear areas of high signal intensity on T1-weighted images consistent with medullary fat in metaplastic
bone. Histopathological examination of the resected specimen revealed a benign ossified soft tissue leiomyoma.
