Living with Pineocytoma

A usually slow-growing tumor of the pineal gland in the brain that can cause headaches and vision problems.

Understanding Pineocytoma

Pineocytoma is a tumor of the pineal gland, a small organ in the brain that makes melatonin, a sleep-regulating hormone.

Pineocytomas are usually slow-growing and rarely spread to other parts of the body. GARD lists adulthood as a typical time for it to appear. Signs include headaches, nausea, fluid buildup in the brain (hydrocephalus), vision problems and Parinaud syndrome.

Signs & symptoms

Symptoms vary from person to person. GARD lists these among the most common:

  • Headache
  • Nausea and vomiting
  • Fluid buildup in the brain (hydrocephalus)
  • Vision problems
  • Rapid, rhythmic eye movements (nystagmus)
  • Memory or thinking problems

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.

Diagnosis

  1. Talk with your doctor

    Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.

  2. See a specialist

    Specialists who may be involved include brain and nervous system specialists and cancer specialists.

  3. Ask which tests can help

    Your care team will decide which exams and tests can confirm the diagnosis.
