Primitive Neuroectodermal (PNET) tumours develop from immature, undifferentiated nerve cells in the brain.

PNET tumours are grade IV, fast-growing and malignant, with the potential to spread throughout the central nervous system. PNET tumours are rare and occur more commonly in children than in adults.  

PNET tumours commonly develop in the cerebrum but can also occur throughout the brain, but always retain the name of a PNET tumour.

For example, a PNET that develops in the cerebellum is not technically a medulloblastoma, and a PNET that develops in the pineal region is not technically a pineoblastoma. This is because PNET tumours behave differently to other tumour types.
