Two cases of osteosarcoma of the femur are presented. In both patients, bone scans confirmed the presence of pulmonary metastases. 99mTc-polyphosphate (TcPP) localizes in the extraskeletal pulmonary metastases, including some not demonstrated radiographically. Thus the TcPP scan is a valuable adjunct in the staging and therapeutic planning of patients with primary malignant bone tumors.
