title: Subperiosteal schwannomas of the femur.
abstract: We report a case of two adjacent femoral subperiosteal schwannomas in a 38-year-old man. To our knowledge, this is the first report of a schwannoma arising as a surface lesion of bone. Radiographs showed focal cortical scalloping and MR imaging two small hyperintense nodules on T2-weighted and STIR images which enhanced with a gadolinium chelate.
