Yesterday, our OB told us there was a 3mm x 3mm X 1mm choroid plexus cyst that had shown on the 20 week scan.

She didn't seem concerned in the slightest, even seemed a little annoyed it had been put in the report. She said that it was very common, and it is something that is a non issue. So much so they don't even follow it up or rescan, as 99.99% resolve on their own and is just a part of development.

We were obviously concerned, and she said it was an isolated cyst and with no other markers or issues it means nothing. My blood work for trisomy 18 and 21 were both greater that 1 in 19,000.

So, stupidly, I googled it when we got home. Trisomy 18 popped up, which made me So anxious! The heart and brain otherwise looked normal, as did the feet. One hand was outstretched, the other was in a fist behind its head. She was determined to get an image of it outstretched, and got one not outstretched but not clenched if that makes sense?

On a side note, DD had a dilated kidney at her 20 week scan which is a soft marker for Downs. By 30 weeks or so it had resolved itself. Logically I know this is also most likely 'one of those things', but I still feel panicked.

Those that had this come up, how did it go for you? Do I listen to my OB and trust it will be ok or do I try and push for a rescan?

As a positive, I managed to stay team green! It was so hard!!!
