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
