I had my much anticipated 20 wk u/s. Measurements were taken and I really did not have a clue that they were looking for "markers". Afterward when I met with my midwife to go over the results she mentioned in passing that a choroid plexis cyst was detected. She moved on and I said wait a minute what does that mean? She said without much concern, "oh, it is a marker for Down Syndrome". You can imagine that I was shocked. She followed this announcement with but you shouldn't worry. Don't worry!

So I did searching on the web, didn't sleep a wink, and in the morning I called her back to ask the questions that haunted me all night. She explained the CPC are commonly found in 20 week u/s (so why did she have to scare me?) and that most will resolve themselves by the 24-28th week. But there is some research to demonstrate a connection between CPC and Downs. So now I feel much better. I am 36 and all other tests were normal and this CPC was the only "marker" detected on the u/s which sounds promising. But why do the doctors need to scare me? I guess if one wanted to have an amnio this might encourage them to have it done. With only one marker we are not going for amnio because we are keeping our baby regardless of the outcome so why worry?

Anyway has this happened to anyone else?
