Hi all,
My first time posting here, but I’m a bit worried and hoping someone who has experienced something similar could put my mind at ease!
I’m pregnant with my first baby, had my 20 week anomaly scan yesterday. So far all scans/tests have come back completely normal; at yesterday’s scan the sonographer told me everything was fine with the baby apart from a small 2cm cyst in his abdomen, and she had no clue what it was. She wanted to refer me straight to fetal medicine for scans/tests that day, but eventually two midwives came to speak to me and said you do need an extra scan, but it won’t be today and unlike the sonographer, they didn’t seem overly worried at all which did put my mind at ease. The report I’ve been given says that every other organ, limb etc appears normal, and funnily enough the cord insertion site, that they’re saying the cyst is close to, has been listed as normal too.
I guess my question is: has anyone else experienced anything similar, and if everything else seemed normal on the scan, am I just getting myself overly worked up about something that could just resolve itself? I’m sick with worry waiting for our appointment with fetal medicine and have managed to convince myself that they’re going to find a long list of problems when we go to see them!
Thank you for reading!

Small cyst found in baby’s abdomen at 20 week scan... should I be as worried as I am?!

Hey! I’m so sorry to hear your daughter is going through the same, it’s such a scary thing to find out when you expect baby to be perfectly fine.
I went for my follow up scan with fetal medicine 2 days after my initial one - the cyst is definitely there but they’ve decided it’s not near the umbilical cord as originally suspected. The consultant did a veryyy thorough scan of the baby and reassured me that there are no other anomalies, which he said was a really good sign. He also said the cyst is really small and he mostly expects it to resolve on its own, but because he couldn’t tell exactly where it was in baby’s abdomen, he can’t completely rule out that there might be an underlying genetic issue!
That was a little worrying to hear and I was offered the amnio test, I think mainly for my own peace of mind, but I can’t stress enough how adamant the consultant was that he wasn’t too worried at all. He said they want to scan again in 2 weeks to check the cyst again, so I took it as a good sign that they’re not in a rush to get me straight back in!
Is your daughter booked in for a follow up scan? If so I really hope that puts her mind at ease - it’s been 6 days since mine and I do feel much better now!
If you have any other questions though please private message me! I know exactly how your daughter must be feeling and I think it helps if you have someone to talk to who’s going through the same thing x
That’s interesting to hear! The doctor who offered it to me was very clear on the fact he was confident this would resolve itself but that we might want to rule anything out, I think he said he had to offer it to us because the risk of miscarriage was lower than the chance that baby might have a genetic condition, but even the chances of that are quite low!
It’s so stressful, I was so lucky to have had a fairly easy pregnancy up to now and now I’m so aware of all the things that could go wrong! My next scan is on Wednesday so fingers crossed all goes well, thank you for being so reassuring though, it’s always nice to hear someone similar has experienced the same and been okay in the end! x
Hello all! Just a quick update to hopefully give you all some reassurance
I had my follow up scan today, and was given good news! The cyst is still there but hasn’t changed, and they do not think it’s linked to a chromosome disorder as baby is growing really well and everything else is normal. They said worst case scenario is he will need a little op when he’s born but they’re really not worried at all.
Really hope you all get good results with your scans/tests and as always if anyone has any questions please just send me a message! I’m always happy to help as I know just how awful it is waiting for news. Sending you all lots of love and good luck x
@alwaysseekingcomfort hi! So so sorry to hear you’re going through the same situation, it’s such a scary time! Hope this is some reassurance to you, my LO was absolutely fine in the end :) at my 36 week scan they said the cyst had completely disappeared, then when he was a few days old he had an X ray to confirm this and they found nothing. I was the same and all I could find online were worst case scenarios but after a few scans my mind was put at ease! I’m really hoping for the same outcome for you and your LO x
