Magnetic resonance imaging findings for this tumor type have rarely been reported. We report a case involving the distal left femur of a middle-aged man and tumoral invasion of the bone, which, to our knowledge, has been previously described only once. He was treated with distal femoral tumor resection and reconstruction with a modular prosthesis. Histopathologic diagnosis confirmed MIFS. We reviewed literature of the diagnostic imaging and bone invasion findings associated with this tumor type.展开更多

Imaging studies showed an exostosis in the femoral neck causing femoroacetabular imping- ement. The patient was diagnosed with coxar- throsis. This case report suggests that femoro- acetabular impingement may accelerate the degenerative process in the hip joint.展开更多
