Abstract
There is a variety of subtypes of astrocytoma that are important to distinguish from the fibrillary-type astrocytic neoplasms because of differences with regard to clinical presentation, prognosis, and ultimately therapy. Probably the most common of these variant tumors is the pilocytic astrocytoma. With the exception of the World Health Organization (WHO) grading schema, pilocytic astrocytomas are generally not graded (1). According to the revised WHO schema for grading astrocytic neoplasms, pilocytic astrocytomas are designated as grade I neoplasms (1).
