Surgical resection of the tumor is the primary treatment modality for choroid plexus papillomas. Gross total resection is curative. For choroid plexus carcinomas, brain invasion can occur, making gross total resection much more difficult, and adjuvant treatment is necessary—radiation used in older children, and chemotherapy is used in younger children. Preoperative chemotherapy has been successful in reducing the vascularity of carcinomas in preparation for surgery. In general, 5-year
survival with choroid plexus carcinomas is approximately 50%. If hydrocephalus persists following tumor resection, a VP shunt may be required.
