This study reports a rare case of pleomorphic xanthoastrocytoma (PXA), a brain tumor, found in the spine. Complete surgical removal led to no recurrence, indicating a positive prognosis for spinal PXA.
Area of Science:
- Neuro-oncology
- Spinal cord tumors
- Neurosurgery
Background:
- Pleomorphic xanthoastrocytomas (PXAs) are rare astrocytic tumors of the central nervous system.
- PXAs typically occur in the supratentorial region of the brain, rarely presenting in the spine.
Observation:
- A 43-year-old male presented with cervical neck pain and radicular symptoms.
- An intradural extramedullary mass was identified at the C5-C6 spinal level.
- The mass was surgically excised and diagnosed as a PXA.
Findings:
- The spinal PXA was completely removed via gross total excision.
- Postoperative imaging at 7 months showed no evidence of tumor recurrence.
- This case highlights successful management of a rare spinal tumor.
Implications:
- Primary intradural extramedullary spinal PXA, though rare, is a treatable condition.
- Gross total excision appears to be an effective treatment strategy.
- Further research into spinal PXA is warranted given its rarity.
