Background:

Pleomorphic xanthoastrocytoma (PXA) is a rare glial tumor typically found in the brain.
Spinal cord involvement by PXA is exceptionally uncommon, presenting unique diagnostic and management challenges.

Observation:

A 60-year-old female presented with progressive left-hand clumsiness and paresthesias.
Neurological examination revealed weakness and proprioceptive deficits, with imaging suggesting an intramedullary astrocytoma or ependymoma.
Histopathological analysis confirmed a diagnosis of spinal pleomorphic xanthoastrocytoma (SPXA).

Findings:

Complete surgical resection of the spinal pleomorphic xanthoastrocytoma was achieved.
Postoperative MRI surveillance at 6, 12, 24, and 36 months showed no evidence of tumor recurrence.
The patient experienced a full recovery of her previous quality of life.

Implications:

Spinal pleomorphic xanthoastrocytomas (SPXAs) exhibit distinct epidemiological features compared to their intracranial counterparts.
Aggressive behavior and neuroaxis dissemination potential necessitate thorough evaluation and complete tumor removal.
Further research, including randomized trials, is crucial for understanding and optimizing the management of SPXAs.
