The choroid plexus is a specialized epithelial tissue that is found in all ventricles of the brain. CSF is mainly produced by the choroid plexus, although a certain fraction is derived directly from the interstitial spaces of the brain. Neoplastic transformation can occur leading to either benign tumors (choroid plexus papillo-mas) or malignant tumors (choroid plexus carcinomas). As expected, these tumors are found within the ventricles. The most common location is the lateral ventricles, followed by the fourth ventricle, then the third ventricle. Although relatively uncommon overall, choroid plexus tumors are more common in infants.
