Pilomyxoid astrocytoma (PMA) is an atypical subtype of pilocytic astrocytoma (PA), which presents in children and young adults. The incidence of PMA is low, so there is no standardized treatment protocol for it. Here, we present a 62-year-old woman with recurrent PMA, which is important for the understanding and treatment of the disease.

Abstract Pilomyxoid astrocytomas (P.M.A) are new class of Pilocytic Astrocytoma (P.A.) which typically have their origin in hypothalamus and chiasmatic region. There are very few case reports of PMAs arising from cerebellum. Their imaging features are similar to PA but they behave more aggressively than PA. The authors report a case of 10 year old male child who presented with right cerebellar tumour diagnosed as PMA on histopathology.

Histological Features

Abstract OBJECTIVE AND IMPORTANCE: Pilomyxoid astrocytoma (PMA) is a recently described, rare, circumscribed glioma similar to pilocytic astrocytoma. Despite its circumscribed nature, PMA implies a worse overall outcome than typical pilocytic astrocytoma. All PMAs reported to date involved the hypothalamic/chiasmatic region. Since these original reports, we have encountered three tumors in the spinal cord with histological features identical to those of PMA. CLINICAL PRESENTATION: We report three male pediatric patients. The first patient presented at age 6 with back pain and constipation. The second patient presented at age 8 with back pain and a bout of urinary incontinence. The third patient, a neonate, presented with respiratory failure and hypotonia. INTERVENTION: The first patient's cervical and thoracic neoplasm was treated with subtotal resection and multiple laminectomies and spinal fusion for recurrence. The second patient underwent gross total resection of his thoracic neoplasm. The neonate underwent laminectomy and biopsy of his holocord tumor. CONCLUSION: 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.
