__NOTOC__
== Overview ==
 
'''Pilocytic astrocytoma''' is a brain tumor that occurs predominantly in children and involves the midline, basal and posterior [[fossa]] structures. It is generally considered a [[benign]] tumor of childhood. It is often [[cystic]] and if solid, it tends to be well circumscribed. It is characteristically a contrast enhancing tumor by current imaging investigations (e.g. [[CT scan]], [[MRI]])
 
Microscopically, the tumor is composed of bipolar cells with long "hairlike" [[GFAP]]-positive processes. [[Rosenthal fiber]]s, [[eosinophilic]] granular bodies and microcysts are often present.
 
It is classified as '''Grade 1 [[Astrocytoma]]'''.
