Extradural cord compression due to metastatic oligodendroglioma.

Extraneural metastases from primary intracranial tumours are extremely rare. We present a case of metastatic oligodendroglioma causing extradural spinal cord compression at the level of the sixth thoracic vertebrae resulting in paraplegia. We discuss the routes of tumour dissemination and possible reasons for the rarity of cases of metastatic oligodendroglioma.
