title: Congenital choroid plexus papilloma of the fourth ventricle.
abstract: A newborn infant with marked hydrocephalus had a large papilloma of the choroid plexus originating in the fourth ventricle and infiltrating the brain stem. The computed tomographic (CT) scan appearance was distinctive, showing vascularity and marked enhancement with contrast medium. Histological confirmation was made from several surgical sites. Total removal of the tumor was not possible. Review of congenital choroid plexus brain tumors reveals the location of this child's tumor in the fourth ventricle to be uncommon.
