Living with Choroid plexus papilloma

A non-cancerous brain tumor that makes extra brain fluid and can cause pressure and headaches.

Understanding Choroid plexus papilloma

Choroid plexus papilloma (CPP) is a non-cancerous (benign) tumor of the choroid plexus, the tissue in the brain that makes cerebrospinal fluid (CSF).

CPPs most often occur in children but can occur in adults. Tumor cells make extra CSF, which can cause hydrocephalus (too much fluid in the brain) and pressure inside the head. Infants, especially with a tumor in the third ventricle, can have hydrocephalus or a larger head size.

Signs & symptoms

Symptoms vary from person to person. GARD says they can include:

  • Headaches
  • Nausea and vomiting
  • Drowsiness
  • Swelling of the optic nerve (papilledema)
  • Vision changes
  • Too much fluid in the brain (hydrocephalus)

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.

  4. Connect with expert centers

    Alex's Lemonade Stand Foundation may keep lists of experts for this condition.
