Choroid plexus papilloma (CPP) is a rare disease affecting mainly children in which a benign tumor is found in the ventricular system of the brain. The most common site for the tumor in children is in the lateral ventricle. Consequently, normal CSF flow is disrupted due to the location of the tumor, creating an increase in pressure within the brain. Patients usually complain of a headache, vision problems, vomiting or seizures. Surgical removal of the tumor is the most common treatment.
