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. Copyright © 1992 American Cancer Society
