Choroid plexus papilloma (CPP) ia a non-cancerous (benign) tumor of the choroid plexus, a network of blood vessels in the brain which surrounds the ventricles and produces the fluid surrounding the brain and spinal cord (cerebrospinal fluid, or CSF).[1] CPPs most commonly occur in children but may occur in adults.[2] Symptoms are generally due to increased secretion of CSF by tumor cells, causing hydrocephalus and subsequent intracranial pressure.[2] Affected individuals may experience headaches, nausea and vomiting, drowsiness, ocular or gaze palsies, optic nerve swelling (papilledema), visual disturbances, and possible blindness. Infants, especially those with a tumor in the third ventricle, can present with hydrocephalus or macrocephaly.[2] Some cases of CPP may result from a mutation in the TP53 gene.[3] Complete tumor removal often cures the condition and may also relieve the hydrocephalus.[1]
