choroid plexus cyst found on u/s- would you follow up or not worry?

I had my 20w u/s yesterday and everything looked great except for the cyst, which measured small by the tech's standards.  My dr. is out for the holiday so I don't think I will hear from her until next week.  The tech said that she had never seen a cyst that had not gone away by the third tri but that they always do a follow up u/s to make sure.  When I researched this online, I found that there is such a weak association with these cysts and any actual problems that it seems like overkill to do another u/s.  We did the AFP quad screen and everything was excellent, very low probability of any genetic problems and I am under 35.  The cysts are actually commonly noted in adult MRIs and have never been linked to any diseases or deformities.  Our midwife and DH think it is silly to be overly concerned and don't see the need for a follow up u/s unless it makes me feel better, which I guess it would if it was all clear.  FWIW, our midwife is not in the habit of ordering u/s's for healthy women and healthy pregnancies for reasons such as this.

As you can tell, I am trying not to worry.  The introduction of the u/s in modern obstetrics has revealed so many intricacies of our anatomy that OBs feel it necessary to be overcautious about and scare us half to death in the process.  During our 20w with DS he had an isolated short femur measurement (~1.5w behind other measurements) and I freaked out for weeks.  We decided not to do another u/s because there was nothing it would really help.  DS has always been of average height and perfectly proportioned so I feel that worrying about this cyst may be silly.  But....

Any thought/experiences?

my son had a 6mm cyst on his 20 week ultrasound.  It was gone by the 28 week ultrasound.  They're apparently very common and I wouldn't worry....not that that'll make you stop, but it's really not a big deal.

DD1 had one as well. We had a follow up u/s with a perinatologist. The cyst was gone and the perinatologist even commented that my obgyn was overreacting by sending me to them when there were no other risk factors other than the cyst. It sounds like in your case there are no other risk factors which makes the likelyhood of anything being a problem very very slim. From experience though I wanted the extra u/s. It was nice to have the peace of mind of knowing it was gone. And if it wasn't then I would have known that as well. Like you said knowing doesn't change anything but atleast I knew. Also this was with dd1 and since she was our first I freaked out about every little thing. :P I am a worrier- and even knowing all the facts and knowing that dd1 had zero risk factors other than the cyst I still couldn't help think of the what ifs and the u/s put all that to rest. Now I'm pregnant with #3 and quite a bit more laid back about it all. I say if you aren't going to worry yourself sick about it and will be at peace not having an additional u/s then there is no need. Hugs mama!

I had a different soft marker come up on my baby's anatomical ultrasound and found great peace of mind in having a repeat u/s done to check up on it.  It was a very short, quick u/s so if it will put your mind at ease then I personally see no harm, only good, in having it done.  Best wishes with your decision :-)
