choroid plexus papilloma
Also written as: CPP
A benign WHO grade I tumor arising from the choroid plexus epithelium, most commonly occurring in the lateral ventricles of children.
Full Definition
Choroid plexus papilloma is a benign intraventricular tumor that develops from the epithelial cells of the choroid plexus, the structure responsible for cerebrospinal fluid production. These tumors are most frequently found in children, particularly infants, and typically arise in the lateral ventricles in pediatric cases or the fourth ventricle in adults. They often present with hydrocephalus due to CSF overproduction or obstruction. Complete surgical resection is usually curative, though the procedure can be challenging due to the tumor's vascular nature and intraventricular location.
Usage
Usage note: Often abbreviated as CPP in pediatric neurosurgical literature.
