Has anyone else had this yet? I went in today for a happy 18 week ultrasound and then I was told that my son has two choroid plexus cysts found in his brain. I now have an appointment scheduled with a Maternal Fetal Specialist for next Wednesday. I had the harmony test done when I was 10 weeks pregnant and it came back that everything was normal, no chromosomal defects. I really don't even understand what it is, but I'm super stressed and sad bc it is something that didn't come back perfect.
Re: Choroid Plexus Cysts found on 18 Week Ultrasound w/ no other abnormalities, anyone? Need advice.
A choroid plexus cyst is not considered a structural or functional brain abnormality. Most choroid plexus cysts are isolated and occur in otherwise low-risk pregnancies.2 The only association of some significance between an isolated choroid plexus cyst and a possible fetal problem is with trisomy 18. Choroid plexus cysts are present in 30% to 50% of fetuses with trisomy 18. Trisomy 18 is characterized by major structural abnormalities and abnormal sonographic findings.3 When a fetus is affected by trisomy 18, multiple structural anomalies are almost always evident, including structural heart defects, clenched hands, talipes deformity of the feet, growth restriction, and polyhydramnios. When a structural anomaly is present in addition to choroid plexus cysts, the probability of trisomy 18 is 37%.4
In the absence of associated sonographic abnormalities, the likelihood of trisomy 18 is extremely low in otherwise low-risk pregnancies.

If they didn't find any other abnormalities, little one is most likely going to be just fine. Especially reassuring, is the low risk results from the genetic testing/Harmony. If Trisomy 18 were present, the test would have raised your odds. Chances are these cysts will resolve on their own and are not of concern. But trust me I understand that it is impossible not to worry. Thoughts and prayers for you and your little one. My money is on a perfectly healthy little baby joining you in October. Hugs
Good luck! I am sure everything is perfectly fine
