What is a Choroid Plexus Tumor?

  • Choroid plexus tumors are a type of brain tumor that grow in the tissue located in the spaces of the brain called ventricles.

    • The choroid plexus makes cerebrospinal fluid (CSF), the liquid that surrounds the brain and spinal cord
    • Choroid plexus tumors are rare, representing only 3 percent of brain tumors in children
    • They’re seen more often in younger children – between 10 and 20 percent of brain tumors that occur within the first year of life are choroid plexus tumors
    • Girls and boys are equally affected
    • The vast majority of choroid plexus tumors are either choroid plexus papillomas (CPP) or choroid plexus carcinomas (CPC). CPP are often easier to treat.
