* Extensively diffusely growing astrocytic neoplasm.
* Depreceated entity.
**Currently considered a rare pattern of diffuse glioma infiltration.
* Was used for extensively diffusely growing astrocytic neoplasms.
**Introduced in 1938 as a post-mortem diagnosis.<ref>SAMUEL NEVIN - GLIOMATOSIS CEREBRI, DOI: http://dx.doi.org/10.1093/brain/61.2.170 170-191 First published online: 1 June 1938</ref>
