I am 37 weeks pregnant and at my 20 week scan I was told my baby had "a single isolated soft marker - a choroid plexus cyst" but ot to worry, as these are the least problematic of the soft markers, and no follow up was needed. However, i was very worrid so was referred to a consultant for a chat, she assured me that although cps are often see in babies with Downs Syndrome or other chromosome abnormalities, they almost always show up along with other markers on the scan. The fact that i only have one is no cause for concern and only gives me a slightly increased chance of the baby having any problems. I'm still v scared though. Just wondered if anyoe else had had this show up on their scan. Thanks x x
