Epidural Chordoma of the Cervical Spine with Secondary Bone Involvement.

A 53-year-old man presented with cervical myelopathy. magnetic resonance imagine (MRI) revealed a predominantly extraskeletal, extradural lesion extending along the posterior aspects of the C2 to C5 vertebral bodies, with greater than 60% spinal canal compromise and severe cord compression. Bone involvement was present, but was thought to be secondary. Based on histopathology and immunohistochemical stains, the final pathologic diagnosis was chordoma. The lesion was treated with embolization, surgical resection, and proton beam radiotherapy, and there was no evidence of recurrence or metastasis after five years.
