title: Giant cell-rich osteosarcoma of the distal femur: radiographic and magnetic resonance imaging findings.
abstract: We report a case of giant cell-rich osteosarcoma in the right distal femur of a 32-year-old man. Giant cell-rich osteosarcomas are sometimes difficult to distinguish from giant cell tumors by age, location, magnetic resonance imaging findings, and pathology. Radiography may be useful in the diagnosis of giant cell-rich osteosarcoma.
