title: An isolated nonosseous metastasis to the epidural space from an osteogenic sarcoma.
abstract: Metastatic disease from osteosarcoma most commonly occurs in the lung and bony sites. Both primary spinal osteosarcomas and spinal metastatic lesions are rare. A case is reported of a nonosseous epidural metastatic lesion from osteosarcoma. It was visualized best by metrizamide-enhanced computed tomographic scanning. The patient symptomatically improved with excision of the lesion although there was massive recurrence despite combined therapy.
