A pineal gland cyst is a usually benign (non-malignant) cyst in the pineal gland, a small endocrine gland in the brain. Historically, these fluid-filled bodies appeared on 1-4% of magnetic resonance imaging (MRI) brain scans, but were more frequently diagnosed at death, seen in 4-11% of autopsies. [ 1 ]

Colloid cysts represent 0.5–1.0% of intracranial tumors. [1] Symptoms can include headache, vertigo, memory deficits, diplopia, behavioral disturbances, and in extreme cases, sudden death. Intermittency of symptoms is characteristic of this lesion. [2] Untreated pressure caused by these cysts can result in brain herniation. [3]
Papillary Tumors of the Pineal Region are located on the pineal gland which is located in the center of the brain. The pineal gland is located on roof of the diencephalon. It is a cone-shaped structure dorsal to the midbrain tectum. [3] The tumor appears to be derived from the specialized ependymal cells of the subcommissural organ.
One review estimated 52% in the posterior fossa, 39% are supratentorial primitive neuroectodermal tumors (sPNET), 5% are in the pineal, 2% are spinal, and 2% are multifocal. [3] In the United States, three children per 1,000,000 or around 30 new AT/RT cases are diagnosed each year. AT/RT represents around 3% of pediatric cancers of the CNS. [4]
