Choroid Plexus Tumor Defined

Originally published on January 22, 2013
Most recently updated on April 10, 2013

The choroid plexus is located within the ventricles of the brain and produces cerebral spinal fluid.  A choroid plexus tumor arises in this location of the brain. They account for approximately 1-3% of pediatric brain tumors and are most common in infants.


  • Choroid plexus papilloma: a non-malignant form of a choroid plexus tumor which grows slowly within the ventricles.
  • Choroid plexus carcinoma: a malignant form of the choroid plexus tumor which commonly grows in the lateral ventricles.


  • Hydrocephalus

Surgery is a common treatment option and if the tumor is malignant, chemotherapy and/or radiation therapy.
