title: Colloid cyst of the third cerebral ventricle with an embryological remnant consistent with paraphysis cerebri in an adult human.
abstract: The histogenesis of colloid cysts of the third ventricle remains unsettled. Initial theories favored a neuroepithelial (paraphysis, ependyma, choroid plexus) origin and some investigators based on morphologic analysis have offered an alternative endodermal source. We report a case of colloid cyst of the third ventricle arising in association with a remnant which we believe corresponds to the paraphysis cerebri in man.
