Tumors of the third ventricle in children (literature review).

Abstract

Tumors of the third ventricle are rare and account for 0.6–0.9 % of all pediatric brain tumors. Tumors of the third ventricle are divided into primary tumors, such as choroid plexus papillomas and ependymomas, and secondary tumors, such as craniopharyngiomas, optic nerve gliomas, pineal tumors, and meningiomas. Choroid papilloma is a common tumor, the treatment of which is mainly based on microsurgical resection. Apart from the many treatment options for craniopharyngiomas, microsurgery is the preferred treatment option. Ependymomas also have several treatment options, with microsurgical removal considered the first line of treatment.
