Spinal meningeal mesenchymal chondrosarcoma. Report of a new case and review of the literature.

ABSTRACT

A case of T12-L2 intraspinal extradural meningeal mesenchymal chondrosarcoma is described in a patient presenting with a clinical history of low-back pain and weakness of the lower limbs. Magnetic resonance T1-weighted Gadolinium enhanced imaging, showed an intraspinal extradural mass, extending from T12 to L2, located anterolaterally into the spinal canal and pushing posteriorly the conus medullaris. The mass was completely removed and postoperative histological diagnosis was of mesenchymal chondrosarcoma. The patient was completely symptoms-free after surgery. Intraspinal meningeal mesenchymal chondrosarcoma and treatment options are reviewed.
