Symptomatic renal metastasis is very rare in osteosarcoma. A few reported
cases had pulmonary metastases before renal involvement. We present a case
of metastatic renal osteosarcoma without pulmonary involvement. The patient
presented with hematuria 8 years after initial treatment of osteosarcoma of
the left distal femur. Computed tomography revealed a bilateral calcified
renal mass. The patient died of disease 4 months after detection of the
metastases. At autopsy, metastatic osteosarcoma was discovered in the
bilateral kidney, both renal veins, inferior vena cava and right atrium.
There was no pulmonary involvement. We emphasize the need for renal
evaluation for the follow-up of patients with osteosarcoma.
