18 weeks pregnant and ultra sound found a Choroid Plexus Cyst?

The doctor called and said they found a choroid Plexus Cyst in the ultra sounds for my unborn son. He said that all other tests that I have done found the baby is fine - no sign of down's ect. However, I have to go in for a level 2 ultra sound to do a more accurate look at everything. He said that most likely everything is fine, but I can't help but be nervous. Has anyone other mother's gone through this? Any advice or information would be great!

18 weeks pregnant and ultra sound found a Choroid Plexus Cyst?
I just went through the same thing. I received the news at 18 weeks that my baby had bilateral choroid plexus cysts. I too am having a boy (can't wait) and I was so upset with the news. My doctor told me not to worry because my NT scan was negative and so was my triple screen test. He sent me for a level 2 ultrasound, just to be safe, and the specialist recommended I have an amnio because of my age (I'm 34). This only caused me more stress and worry. The results came back and the baby was healthy. I just went back to the specialist for check up at 22 weeks and the cysts are gone. The specialist stated he sees the cysts in approximately 1 out of 12 fetuses. As long as you do not have any other risk factors, I wouldn't worry. These cysts usually clear up by week 24.
Reply:Hi,


I don't exactly know what type of cyst that is...but I had a cyst during the first tri which most women get and they said it is fine and wont hurt my little one. I don't know of a cyst hurting a baby. If the doc says it's most likely fine just keep those words in, they just have to make sure to protect them, you, and your son...
Reply:i've heard of women getting a cyst during pregnancy and they said it'll usually go away by 6 months and if not the DR will have to remove it.
Reply:I had never heard of it until your question. I was curius so I looked it up. Here is what I found:





The choroid plexus is the tissue within the brain, which produces the cerebrospinal fluid. This fluid fills the normal spaces in the brain (ventricles) and flows around the outside of the brain and spinal cord. Small fluid-filled spaces, called cysts, are seen during obstetrical ultrasound examinations in the choroid plexus in up to 2% of normal pregnancies.





These cysts disappear spontaneously during pregnancy and are, in themselves, of no concern before or after birth. There is no need to re-scan during pregnancy. Children with choroid plexus cysts are developmentally normal and indistinguishable from those in whom no cysts were seen on ultrasound examination during pregnancy.





In a few patients reported in medical journals, a fetus with choroid plexus cysts was found to have a chromosomal abnormality, Trisomy 18. In Trisomy 18, the fetus has an extra chromosome number 18 with a total of 47 chromosomes, instead of the normal 46. The great majority of babies with this condition have other physical abnormalities, often affecting the limbs (especially a clenched fist), heart, brain, and/or face. When these defects are found in addition to choroid plexus cysts, there is a strong concern about Trisomy 18, and the mother would be recommended to have an Amniocentesis to determine if the fetus has this condition.





There is considerable controversy in the medical journals about how great a risk of Trisomy 18 or other chromosomal abnormalities there is for a fetus with choroid plexus cysts. This is especially for the fetus that appears otherwise normal by ultrasound and has no other risk factors; such as mother's age, a family history of chromosome problems or an abnormal screening blood test called (Maternal Serum Screen). The size, number and eventual disappearance of these cysts did not alter the risk.





If a fetus with choroid plexus cysts has a detailed ultrasound, including views of the heart and of hands that open and close, and shows no other abnormalities, then the risk of Trisomy 18 is only 1 in about 250. The risk of an Amniocentesis causing a miscarriage is about 1 in 250.





Maternal age (mother’s age over 32) is a significant risk factor as well as other ultrasound signs. The risk of chromosome abnormalities increases significantly when CPC’s are associated with other markers rising from less than 1 in 250 as an isolated finding in a woman under 32 years to 1 in 10 when associated with other markers or raised maternal age.





Based on the medical literature and our experience, we do not recommend Amniocentesis in cases with choroid plexus cysts as the only risk factor. We do believe, however, that Amniocentesis is certainly not inappropriate and can justifiably be performed because of parental concern, even for a small isolated choroid plexus cyst.
