Overview

Gliomatosis cerebri may be classified into several subtypes based on the origin (primary and secondary) and the type of tumor cell (astrocytic, oligodendroglial, and mixed).

Classification

Based on the origin

Gliomatosis cerebri may be classified based on the origin into two subtypes:^[1]^[2]^[3]^[4]


Type of gliomatosis cerebri	Characteristic features

Type 1 (Primary)	No pre-existing primary cerebral neoplastic lesion (de novo) No discrete mass Diffuse spread of tumor More common Median age at diagnosis is 56 years Mean survival time was longer than type 2 (24 months) Predominantly low-grade
Type 2 (Secondary)	Results from a pre-existing cerebral glioma Discrete mass with diffuse CNS involvement Less common Median age at diagnosis is 44 years Mean survival time was shorter than type 1 (21 months) Predominantly high-grade IDH1 mutation is more common

Based on the type of tumor cell

Gliomatosis cerebri may be classified based on the predominant tumor cell type into three sub-types:^[4]
