CPP with similar cytogenetic profiling and differs only by

exhibiting increased proliferative activity. CPCa is a genetically

distinct tumor group.

CPPs are 5-10x more common than CPCs. All CPTs can spread

diffusely through the cerebrospinal fluid (CSF), so the entire

neuraxis should be imaged prior to surgical intervention.

Other neuroepithelial tumors: These rare neoplasms include

astroblastoma, chordoid glioma of the 3rd ventricle, and

angiocentric glioma.

Neuronal and mixed neuronal-glial tumors: Neuroepithelial

tumors with ganglion-like cells, differentiated neurocytes, or

poorly differentiated neuroblastic cells are included in this

heterogeneous group. Ganglion cell neoplasms

(gangliocytoma, ganglioglioma), desmoplastic infantile

ganglioglioma or astrocytoma (DIG/DIA), neurocytoma
