Multiple choroid plexus cysts occur in fetuses, with a prevalence of 2.5% to 4.0% in fetuses with trisomy-18 and are well demonstrated with prenatal ultrasonography in the second trimester. 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).
