Contact the Department of Neurosurgery

Arachnoid cysts are fluid-filled collections between the brain or spinal cord and the arachnoid membrane, one of three membranes covering the brain and spinal cord.

  • The cysts contain normal spinal fluid that likely accumulates in early development before birth
  • Arachnoid cysts are very common
  • Most form on the brain; spinal cord cysts are much more rare
  • Males are four times more likely to have arachnoid cysts than females
  • Most do not need treatment and have no effect on brain development
