Abstract

Pilocytic astrocytoma (PA) is the most common Central Nervous System (CNS) tumor in the pediatric population. It is regarded as a Circumscribed Glioma, due to its benign course. PA is a well-circumscribed, typically cystic lesion with a hyper-intense mural nodule. It shows a slow rate of growth and low cellularity. PA arises mostly in the cerebellum, optic pathway and hypothalamic/ chiasmatic region. We report an unusual case of PA dissemination from the posterior fossa to the  spinal canal in a 16 year old teenager.
