Pilomyxoid Astrocytoma of the Spinal Cord: Report of Three Cases

Abstract

PMAs typically occur in the hypothalamic region and within the first 4 years of life. Tumors with identical histological features are being recognized outside this typical clinical setting. The cases presented in this report suggest that PMA can occur at a later age and can involve the spinal cord. We believe that increased recognition of these circumscribed gliomas will help to elucidate their nature and lead to better management decisions.
