Intradural osteogenic sarcoma in the lumbar spine.

ABSTRACT

To our knowledge, this is the third reported case of spinal intradural osteogenic sarcoma. The two prior reported cases had a history of iophendylate injection whereas this patient did not. Other cases involved the cranial meninges, not the spine. This is the first reported case of intradural osteosarcoma in the absence of iophendylate injection. We report our workup, diagnosis, and treatment. We also include a video demonstrating the intraoperative invasion of tumor and dural erosion.
