choroid plexus papilloma
A rare benign tumor arising from the choroid plexus epithelium, most commonly occurring in the lateral ventricles of children.
Full Definition
Choroid plexus papilloma is a WHO grade I tumor that originates from the epithelial cells of the choroid plexus, the structure responsible for cerebrospinal fluid production. These tumors are most common in infants and young children, typically arising in the lateral ventricles. In adults, they more commonly occur in the fourth ventricle. The tumors often present with hydrocephalus due to CSF overproduction or obstruction. Symptoms may include increased intracranial pressure, developmental delays in children, or focal neurological deficits. Complete surgical resection is usually curative, though the procedure can be challenging due to the tumor's vascular nature and intraventricular location.
