I am posting to share something that happened during my routine anatomy scan that was very scary, but had a good outcome. I had never heard of this before, and it’s not terribly rare, so chances are some of you have or will have experienced this.
I went in at 17w5d for an anatomy scan, even though we don’t want to know the baby’s gender. They found something called Isolated Choroid Plexus Cyst. It is something that happens in about one of every 100 normal live births. What happens is that the part of the brain that produces CSF (cerebrospinal fluid) sometimes ‘pinches’ off little bubbles of fluid during development and form cysts that appear on an ultrasound. The concern is that this particular condition is found in babies who have Trisomy 13 or 18. Typically, when one of these conditions is present, virtually ALL other body systems are affected.
During my NT scan as well as this anatomy scan, no other abnormalities or malformations were noticed. I had also had blood drawn for routine screening (Cystic fibrosis carrier screen, as well as AFP (alphafetoprotein) for Trisomies 13, 18, 21 and neural tube defects) but the results of those labs had not come back yet.
The doctor was not necessarily concerned that my baby would have any of these conditions, but he couldn’t rule it out in the absence of negative blood screening. He was wonderfully thorough, and even encouraged me to google isolated CPCs (choroid plexus cysts). Now, I don’t know about you, but I’ve never in my life encountered a doctor who WANTED me to google anything. He even gave me his e-mail address so I could ask questions after I got more information.
Of course, predictably, after a lot of online research, I had a list of questions. I send the following questions:
Q-What happens if my bloodwork comes back unfavorably? Do we do an amnio, or do we wait and see if there are any other caueses for concern?
He answered: If the risk for trisomy 18 (or other aneuploidy like Down) does come back elevated, we would discuss with you and the father next test. Traditionally it has been amniocentesis but amniocentesis has risks with a risk of pregnancy loss of 1 in 300 (for every 300 procedures we expect 1 pregnancy loss). At this point, we would involve genetics counseling before doing any more testing. There are maternal blood tests that has come on the market in the last year that seems to be very specific about the risk of Down and Trisomy 18 (without the risks of amniocentesis). One of the test is called Materna21 – all these tests are generically called noninvasive prenatal test (NIPT)
Q-If my bloodwork does not show an elevated risk and there are no other developmental anomolies, what happens if the cycsts do not spontaneously resolve?
He answered: The cysts that we have seen over the 23 years [of practice] have always resolved. So I can’t answer what would happen if it does not.
Q-Does the presence of these cycst have any long term impact on the brain development? What about lasting effects after birth?
He answered: Since the cysts have always resolved, we don’t have any data that it interferes with normal brain development.
I got a call back today that my blood tests came back, and I screened negative for everything. I can’t begin to tell you what a relief that was! I also want to give a MAJOR shout out to the April Mamas as well as MrsCarnival, and a few others who showered me with support, kind words of encouragement, and of course lots of thoughts & prayers over the last day. I don’t know how I could have maintained my sanity without them!
I wanted to share my experience with you in the event any of you encounter something similar, or have been through this yourselves. If you made it through my novel, thanks for reading. I hope that nobody has a scare like this in their pregnancy, but know that if you do, you’re not alone. You’re not the first or last person to have a bump in the road. I don’t know if I will give birth to a healthy baby or carry to term, but I do know that right now, I have no cause for concern. I am thankful that I’m pregnant and so far, everything looks good.
