Spinal intradural myxoid chondrosarcoma.

The authors present a rare case of intradural extramedullary spinal chondrosarcoma. This 38-year-old man presented with urinary retention and lower-limb weakness. Magnetic resonance imaging demonstrated a thoracic intradural extramedullary spinal tumor, which was resected. Histopathology revealed a meningeal myxoid chondrosarcoma. Despite adjuvant radiotherapy, the patient had multiple recurrences and metastases and died 18 months following his first surgery. The management of the rare entity of spinal canal chondrosarcoma is discussed.
