This category of cysts takes over areas of necrotic tissue in the brain from injuries, diseases, or abnormalities, which occur due to the central nervous system's nonregenerative nature.
These cysts can affect all germ layers of the CNS, but are most common in the arachnoid mater, and the ventricular space, which may block CSF pathways.
These cysts can be static (stationary) or progressive.
Some examples of cysts originating from the CNS tissue include:
Arachnoid cysts (Leptomeningeal cysts)
Ependymal cysts
Cystic cerebellar astrocytomas
Colloid cysts
