Choroid plexus cysts? Worried for my sister?

[laznacko]

My sister is 30 years old and she is pregnant 21 weeks. She has a healthy daughter 3 y old. At ultrasound screening the GYN saw choroid plexus cysts on the both sides. Everything else looked normal. She made an amnio and now we are expecting the results. Does anybody in this forum had the same experience? Please give me some hope. I`m very very worried for my sister and the baby. We hope the caryotype will be normal because these cysts are the only soft marker the doctor saw.

Thank you very much. You helped me...I know that the risk is small but when it is about someone close just 1 percent risk looks like 100 %. I try to calm my sister too. Thanks again........

Try not to worry.  At my anatomy scan, done at 20 weeks, my baby had 5mm choroid plexus cysts on both sides, which they refer to as bilateral.  I did not have an amnio because I was scared of the risks. I did see a perinatologist at 26 weeks, and he reported that the cysts had resolved, they were completly gone. Everything else with my baby is completly normal.  The fear with choroid plexus cysts (cpc's) is trisomy 18.  With trisomy 18, my perinatologist told me that you would expect to see other abnormalities. You would expect to see slowed growth by a significant amount, you would expect to maybe see something wrong witht he hands- there is a stereotypical overlapping over fingers.  Based on what you told me everything else on the scan was just fine, so I would not worry at all. With that said, I was in agony, tears and the whole bit. I was terrified. But, the cysts went away in my baby, and I am sure that they will in your sisters baby as well.  From what I have read and from what the doctors told me the cysts almost always resolve on their own with no ill effects. It is only quite rarely that there is an association with trisomy 18, and even then you woul expect to see something else wrong on the scan- which your sister didnt from what you said. All that long winded response to try and say, don't worry. I almost drove my self to the grave with worry, don't do the same to yourself, the cysts will probably be gone at her next ultrasound, I would bet money on it.
