Pineocytoma



Other Names:
Pinealocytoma; Pinealoma

A pineocytoma is a tumor of the pineal gland, a small organ in the brain that makes melatonin (a sleep-regulating hormone). Pineocytomas most often occur in adults as a solid mass, although they may appear to have fluid-filled (cystic) spaces on images of the brain. Signs and symptoms of pineocytomas include headaches, nausea, hydrocephalus, vision abnormalities, and Parinaud syndrome.[1] Pineocytomas are usually slow-growing and rarely spread to other parts of the body.[2] Treatment includes surgery to remove the pineocytoma; most of these tumors do not regrow (recur) after surgery.[3]

This table lists symptoms that people with this disease may have. For most diseases, symptoms will vary from person to person. People with the same disease may not have all the symptoms listed. This information comes from a database called the Human Phenotype Ontology (HPO) . The HPO collects information on symptoms that have been described in medical resources. The HPO is updated regularly. Use the HPO ID to access more in-depth information about a symptom.

Because pineocytomas are quite rare, there are no consensus guidelines on the best treatment for these tumors.[4] However, surgery to remove the entire tumor is considered the standard treatment. Because these tumors are located deep in the brain, it is important that the risks of surgery be carefully considered in each person.[3]  Radiation therapy is sometimes used following surgery to destroy any tumor cells that may remain, but the benefit of this additional treatment is questionable.[4]

Research helps us better understand diseases and can lead to advances in diagnosis and treatment. This section provides resources to help you learn about medical research and ways to get involved.

Clinical Research Resources

  • ClinicalTrials.gov lists trials that are related to Pineocytoma. Click on the link to go to ClinicalTrials.gov to read descriptions of these studies.

    Please note: Studies listed on the ClinicalTrials.gov website are listed for informational purposes only; being listed does not reflect an endorsement by GARD or the NIH. We strongly recommend that you talk with a trusted healthcare provider before choosing to participate in any clinical study.

Support and advocacy groups can help you connect with other patients and families, and they can provide valuable services. Many develop patient-centered information and are the driving force behind research for better treatments and possible cures. They can direct you to research, resources, and services. Many organizations also have experts who serve as medical advisors or provide lists of doctors/clinics. Visit the group’s website or contact them to learn about the services they offer. Inclusion on this list is not an endorsement by GARD.

Organizations Supporting this Disease


These resources provide more information about this condition or associated symptoms. The in-depth resources contain medical and scientific language that may be hard to understand. You may want to review these resources with a medical professional.

Where to Start

  • The National Cancer Institute provides the most current information on cancer for patients, health professionals, and the general public.

In-Depth Information

  • The Monarch Initiative brings together data about this condition from humans and other species to help physicians and biomedical researchers. Monarch’s tools are designed to make it easier to compare the signs and symptoms (phenotypes) of different diseases and discover common features. This initiative is a collaboration between several academic institutions across the world and is funded by the National Institutes of Health. Visit the website to explore the biology of this condition.
