Choroid Plexus Cyst

Choroid plexus cysts are cysts formed within the choroid plexus of the brain. They are small fluid-filled spaces formed in the choroid plexus of the brain and are present on both sides of the brain. The choroid plexus makes cerebrospinal fluid within the brain and spinal cord. A choroid plexus cyst is formed when fluid becomes trapped within the layers of the choroid plexus. It is a normal condition and does not cause any harm in babies, children, and adults.
