The fetal choroid plexus produces CSF that leads to the normal expansion and development of the ventricular system. In some cases, fluid may get trapped, leading to the identification of choroid plexus cysts (CPCs) during prenatal ultrasound. The natural history of CPCs is resolution by 28 weeks. CPCs are not considered a structural brain abnormality, but are present in fetuses with trisomy 18 along with other multiple anomalies. An isolated CPC is a common finding in euploid fetuses.
If CPCs are seen in isolation with no other fetal abnormalities on ultrasound
If other anomalies or findings associated with Trisomy 18 are present on fetal ultrasound
Note: SMFM guidance does not recommend diagnostic testing for isolated soft markers if aneuploidy screening is negative, but supports offering diagnostic testing as an option to all pregnant people regardless of aneuploidy risk
Choroid plexus cysts are present in 1 to 2% of all fetuses in the 2nd trimester and are due to CSF trapped in the choroid plexus(es). They may be single, multiple, unilateral or bilateral. CPCs are associated with trisomy 18, not Trisomy 21. CPCs generally resolve and if found in isolation are considered a normal variant.
