Abstract
BackgroundChoroid plexus tumors are rare intraventricular tumors. Most of these tumors are benign choroid plexus papillomas. Choroid plexus carcinoma is the most malignant choroid plexus tumor and constitutes a small percentage of these tumors. The most common location of these tumors is the lateral ventricle and fourth ventricle in pediatric and adult patients respectively. Rare locations such as the third ventricle are reported in the literature with 55 reports of choroid plexus papilloma and just 3 cases of carcinoma located in the third ventricle. Case descriptionWe present an extremely rare case of choroid plexus carcinoma of the third ventricle in a 9 months old boy which was resected successfully through transcortical-transforaminal approach along with a review of literature available around different aspects of these tumors. ConclusionChoroid plexus carcinomas even in rare locations such as the third ventricle can be effectively resected through the transcortical-transforaminal approach, although post-operative subdural effusion can be a potential complication.

Choroid plexus papillomas consist the majority of choroid plexus tumors and choroid plexus carcinomas account for a small percentage of these tumors
Summary
A highly malignant tumor such as CPC in a surgically challenging location such as third ventricle can be managed effectively and safely through transcortical-transforaminal approach. A wellknown drawback of this approach is post-operative subdural effusion that can be managed on an individualized basis.
