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]
Some cysts in the CNS can be asymptomatic (producing or showing no symptoms), depending on their location in the brain or spinal cord. If the cysts develop in critical areas of the central nervous system, they can present one or more of the following symptoms: [6] Pressure in the spinal cord or brain Rupture of nerves around the cyst
The books lists ICD-O codes, CNS WHO grades and describes epidemiological, clinical, macroscopic and histopathological features, among others. [2] The following is a simplified (deprecated) version of the fifth edition.
Pineocytoma, is a rare, benign, slowly growing tumor of the pineal gland. The pineal gland is a small endocrine gland close to the center of the brain that secretes melatonin into the bloodstream. Pineocytomas can cause pressure and fluid build-up in the brain. They are more common in adults.
A pinealoma is a tumor of the pineal gland, a part of the brain that produces melatonin. If a pinealoma destroys the cells of the pineal gland in a child, it can cause precocious puberty . Signs and symptoms
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]
Pineoblastoma is a malignant tumor of the pineal gland. A pineoblastoma is a supratentorial midline primitive neuroectodermal tumor. [2] Pineoblastoma can present at any age, but is most common in young children. They account for 0.001% of all primary CNS neoplasms. [3]
