Dorsal cyst of holoprosencephaly. This communicates directly with the prosencephalic, telencephalic, or diencephalic ventricle. This cavity usually abuts the cranial vault in the midline parieto-occipital area and lies directly on the cerebellum because of tentorial dysplasia. With lobar holoprosencephaly, this cyst may occur on one side.

Most cerebral cysts are congenital, meaning children are born with them. But sometimes they can develop in adults after head injuries, meningitis, tumors, or brain surgery. Some children born with cerebral cysts have no symptoms; in other cases, it may take years for the first symptoms to appear.
Arachnoid cysts are cerebrospinal fluid-filled sacs that are located between the brain or spinal cord and the arachnoid membrane, one of the three membranes that cover the brain and spinal cord.
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) and elevated brain pressure.
Posterior fossa arachnoid cysts are enclosed by the pia and arachnoid layers of the meninges, and their contents have the same consistency as CSF. They do not communicate with the fourth ventricle or with the subarachnoid space in the posterior fossa. They are more commonly detected by routine prenatal ultrasound.
A colloid cyst is a benign, fluid-filled sac that arises in the area of the brain known as the third ventricle. The common surgical treatments for colloid cyst are shunt placement, craniotomy, and endoscopic craniotomy; in some cases only observation is necessary.
Synovial cysts are abnormal fluid-filled sacs in joints in the spine. These cysts are benign, which means they are not cancerous. Synovial cysts typically develop as a result of degenerative changes that occur with aging. They can be found throughout the spine, but are most common in the lumbar region (low back).
Facet cysts or synovial cysts, are fluid-filled sacs located in the joints of the spine. They typically develop as a result of a degeneration of the spine. This is most commonly due to age. While they can be found throughout the spine, they are most commonly located in the lumbar region.
Facet joint cysts, also called synovial cysts, are benign, fluid-filled sacs that develop due to degeneration of the facet joints of the spine.

The wall of the cyst is a thin transparent membrane consisting of ependymal epithelium and leptomeninges, in which, occasionally, a layer of cerebral tissue or heterotopic glial rest is seen.
