Colloid Cyst

A colloid cyst is a slow-growing tumor typically found near the center of the brain.

If large enough, a colloid cyst obstructs cerebrospinal fluid (CSF) movement, resulting in a build up of CSF in the ventricles of the brain (hydrocephalus “water on the brain”) and elevated brain pressure.


  • Most patients experience headaches, although other symptoms can occur.
  • If symptomatic, prompt surgical treatment may be required in order to reduce the relatively high risk of sudden death.

Treatment options may include endoscopic surgery or an open craniotomy via the corpus callosum of the brain.
