Childhood multifocal osteosarcoma--diagnosis by 99mtechnetium bone scan: a case report.
A 14-year-old boy with osteosarcoma presented with evidence of a solitary bone lesion by clinical and radiographic examination. A preoperative 99mtechnetium bone scan revealed multiple skeletal osteoblastic abnormalities and upon biopsy of one of these lesions, the diagnosis of multifocal osteosarcoma was established. This unusual case dramatically illustrates the value of 99mtechnetium bone scan in preoperative staging of patients with osteosarcoma.
