Overview

Astrocytoma may be classified according to its histology into 4 grades: pilocytic astrocytoma, diffuse astrocytoma, anaplastic astrocytoma and glioblastoma multiforme.

Classification

Astrocytoma may be classified according to its histology into 4 grades:^[1]^[2]

Astrocytoma

Low grade

High grade

Pilocyic astrocytoma

Diffuse astrocytoma

Anaplastic astrocytoma

Glioblastomas multiform

+Astrocytoma may be classified according to its [[histology]] into 4 grades: [[pilocytic astrocytoma]], [[diffuse astrocytoma]], [[anaplastic astrocytoma]] and [[glioblastoma multiforme]].
 ==Classification==
-Within the astrocytomas, there are two broad classes recognized in literature, those with:
-* Narrow zones of infiltration (mostly invasive tumors; e.g., pilocytic astrocytoma, subependymal giant cell astrocytoma, pleomorphic xanthoastrocytoma), that often are clearly outlined on diagnostic images

-* Diffuse zones of infiltration (e.g., low-grade astrocytoma, anaplastic astrocytoma, glioblastoma), that share various features, including the ability to arise at any location in the CNS, but with a preference for the cerebral hemispheres; they occur usually in adults; and an intrinsic tendency to progress to more advanced grades.<ref> http://emedicine.medscape.com/article/283453-overview </ref>
