Primary Anaplastic Cerebellar Pilocytic Astrocytoma

Abstract

A case of primary anaplastic pilocytic astrocytoma (PA) and its clinicopathologic and radiologic features are reported. PA is a World Health Organization grade I tumor typically affecting children and young adults. Initial presentation of a PA with anaplastic features is particularly uncommon, and making a definitive diagnosis of primary anaplastic PA can be challenging. Increased recognition of primary anaplastic PA may prove useful for the clinical course and therapeutic stratification.
