WebThe choroid plexus is the part of the brain that makes cerebrospinal fluid, the fluid that normally bathes and protects the brain and spinal column. Valle DE, Borne JA. Aside from advanced maternal age, two of the most common reasons for referral for a genetic sonogram are fetal choroid plexus cysts (CPCs) and echogenic intracardiac foci (EIFs). The choroid plexus is the part of the brain that makes cerebrospinal fluid, the fluid that normally bathes and protects the brain and spinal column. The name cyst is sometimes applied erroneously to a midline ventricular diverticulum without true separation from the ventricular system, which can be found in holoprosencephaly or in Dandy-Walker syndrome. monosomy X (45XO) Search for more papers by this author.
