SIMAL-JULIAN, J.A. et al. Spinal pleomorphic xantoastrocytoma: Case report. Neurocirugía [online]. 2010, vol.21, n.5, pp.390-395. ISSN 1130-1473.

Introduction. We report the clinical, radiological and pathological features of a spinal pleomorphic xanthoastrocytoma, an unusual neoplastic entity in a really rare location, establish an appropriated management of these lesions and review the short available english literature. Case report. A 60 years old woman consulted with doctor because she felt progressive clumsiness accompanied by occasional paresthesias on her left hand. Neurological examination showed up weakness and slight propioceptive disturbances. The differential imagine diagnosis was established between intramedullary astrocytoma and ependimoma. Patient underwent surgical gross total remove. Histopathological examination confirmed the diagnosis of pleomorfic xanthoastrocytoma. We performed MRI controls at 6, 12, 24 and 36 months that did not reveal recurrence. Nowadays, the patient has regained her previous quality of life. Discussion and conclusion. Comparing to published cases about intracranial pleomorphic xanthoastrocytomas, spinal pleomorphic xanthoastrocytomas (SPXA) present different epidemiological characteristics. The known SPXAs affected to cervical and/or high thoracic levels. The hypothesis about a more aggressive behaviour of PXA in spinal cord may be corroborated after literature review. Extension examination is mandatory since dissemination along the neuroaxis has been described. Removal extension is crucial in the prevention of tumour recurrence. Adyuvant radiotherapy should only be considered when there is postoperative residual tumour and/or anaplastic features. Randomized clinical trials or databases are necessary to know all the aspects of this pathological entity.
