Definitions

Tumours of the central nervous system
ICD-O-3 topography code: C70, C71 and C72

Angiocentric glioma is a newly identified, epilepsy-associated, stable or slowly growing brain tumour primarily affecting children and young adults. It is preferentially located in the cerebral cortex. Histopathologically the tumor is composed of monomorphous, bipolar glial tumor cells that are oriented along vascular structures and along the subpial region. The tumors have an infiltrative character. Their precise derivation has not been firmly established, but ependymal features are conspicuous 1
