Abstract

Primary leiomyosarcoma (LMS) of the bone is a very rare tumor with smooth muscle differentiation on immunohistochemical studies. Radiologically, LMS appears as an osteolytic lesion with aggressive features but no pathognomonic radiological findings that helps making the diagnosis. We report one case of primary LMS of the femur with fluid-fluid levels (FFLs) on the MRI, the first case to our knowledge. We consider we should include primary LMS of the bone in the differential diagnosis of “FFL” lesions.
