Intramedullary spinal cord and leptomeningeal metastases from intracranial low-grade oligodendroglioma.

We present an unusual case of a patient with an intracranial low-grade oligodendroglioma who developed recurrence with an intramedullary spinal cord metastasis and multiple spinal leptomeningeal metastases. The intramedullary spinal cord metastasis showed mild enhancement similar to the original intracranial primary, while the multiple spinal leptomeningeal metastases revealed no enhancement. This is the seventh reported case of symptomatic intramedullary spinal cord metastasis from a low-grade oligodendroglioma.
