A schwannoma is a benign nerve sheath tumor commonly located in soft tissue. An intraosseous schwannoma is very rare, and only four cases involving the femur were found in a review of the English-language medical literature. We present a rare case of a schwannoma with well-defined, lytic, dumbbell-shaped and benign-appearing lesions of the proximal femur.
