Choroid plexus tumors in children and young adults: report of 16 consecutive cases

Choroid plexus tumors are rare intraventricular tumors, and they represent 2-4% of brain tumors in children. This single-institution retrospective stu dy involves 16 consecutive choroid plexus tumors: 13 papillomas and 3 carci nomas. Tumor locations were the lateral ventricles in 13 cases, the third v entricle in 2 cases and the fourth ventricle in 1 case. The mean age at pre sentation was 3.1 years. Two patients died of perioperative blood loss. Fiv e-year survival was 85% with papillomas and 33% with carcinomas. None of th e papillomas recurred after total tumor resection, and the functional outco me in long-term survivors after papilloma surgery was excellent in 92% of t he cases, Two of the carcinoma patients had disseminated disease. Fifty per cent of the patients had persistent hydrocephalus after tumor resection, an d these required cerebrospinal fluid diversion.
