Choroid plexus papilloma (CPP) are rare in adults and accounted for only 0.4-1% of all intracranial tumors and even though found in all age groups, it is first of all a pediatric tumor--in children of the first year of life they account for 12-14% of all brain tumors. The preferential localization of CPP--lateral ventricles of the brain. Our paper describes a rare case of an infant with a "migrating" choroid plexus papilloma of the lateral ventricle and reviews modern approaches to surgical treatment.
