Arachnoid cyst

Arachnoid cysts are cerebrospinal fluid covered by arachnoidal cells and collagen that may develop between the surface of the brain and the cranial base or on the arachnoid membrane, one of the three meningeal layers that cover the brain and the spinal cord.

Most cases of primary cysts begin during infancy; however, onset may be delayed until adolescence.
