Cardiac metastases from osteosarcoma. A report of two cases.

Two children who developed cardiac metastases from osteogenic sarcoma are described, and the value of computed tomography in making an antemortem diagnosis is illustrated. Computed tomographic images with a narrow window width will reveal the presence of calcification within the cardiac metastases. Images in this mode should always be studied in patients with osteogenic sarcoma who are undergoing chest computed tomography scans to detect pulmonary metastases.
