Intraspinal mesenchymal chondrosarcoma

Abstract

✓ A 52-year-old man presented with symptoms of progressive cervical radiculomyelopathy. A myelogram showed an intradural block at the C-6 level. Magnetic resonance T1-weighted imaging revealed a hypointense, sausage-shaped mass extending from C-3 to C-6, located posterolaterally on the right side and pushing the spinal cord to the left and anteriorly. At surgery, a mass was found attached solely to the pia mater, with a normal arachnoid and dura mater overlying it. The mass was excised completely and microscopic examination identified a mesenchymal chondrosarcoma. The patient was symptom-free 6 months after surgery.
