Choroid Plexus Cyst on 18Wk Fetus' Brain

I am 30 years old and am 18 weeks pregnant with my second child. I had a routine ultrasound performed yesterday and they found a choroid plexus cyst on the baby's brain. I am having a level II ultrasound done to check for fetal abnormalities but have to wait almost 2 weeks until the appointment. I am consumed with worry and am just looking to see if others have had similar findings during ultrasounds.

The same thing happened to a good friend of mine... by the time they had a follow up ultrasound, the cyst had resolved. Today, they have a very spunky 23 month old.

here is a link to a site of a couple with the same diagnosis at 17 weeks and the child is fine.

i will keep you and your baby in my prayers for a safe and healthy delivery. T.

I have 3 children ages 19, 17 and 13. My 2 youngest both had those cysts and are perfectly healthy - never been any problems. Our pedi told us they go away on their own.

S.,
This is very common. They found the same thing on my ultrasound, 18 weeks also and everything was fine. My son is now almost two and a totally healthy. I was told that it is a developmental stage and they burst on their own. Hope this eases ome of your nervousness. I also was very worried.

Hi S.,
I've never heard of this particular condition. Pregnancy is supposed to be a wonderful, exciting time in a woman's life and I'm sure you're probably upset and possibly frightened right now. Try to stay calm and think positive thoughts (hard, I know). I googled (not always the best idea) the condition and found this blurb:
It is believed that many adults have one or more tiny CPCs.[1]

CPCs have no impact on an individual's health or development or learning. The fetal brain may create these cysts as a normal part of development. They are temporary and usually are gone by the 32nd week of pregnancy.

Hope that helps a little. I'll pray for you. Best of luck.
Hugs,

Hi S.,

My daughter had CPCs, too. Everything else was normal (head shape, fingers, feet, gut, etc.) and my Maternal/Fetal specialist advised against an amnio since my level 2 results came back excellent. At 26 weeks, the cysts diappeared (as expected) and my 3 year old is PERFECT! Also, my OB/GYN told me that in the case of an otherwise normal ultrasound but seeing CPCs, she has never seen them NOT go away. So, assuming all else is ok, do your best to relax until you get to week 26 or so. It will be hard, but do you best.

We had the same experience with our oldest. I believe he had 4 cysts. The good news is that (from what we were told) they usually disappear by week 26.
I obviously cannot say with absolutes, since I am no doc, but can only share what we learned.
Question: DId they see any additional abnormalities in the initial ultrasound? (extra fold of skin at the base of neck, heart problems, normal fetal head & body size, etc.?) I know that is why they are doing the 2nd, to make sure, but for your reassurance, I remember wanting to grasp on to any hopeful bit of info. If they didn't already see anything else that could be a problem, then try not to worry too much until they tell you there is a problem. (I know - easier said than done).
I worried like crazy & my husband was totally cool since they told us they would probably go away. Fortunately for our son, he didn't have any other issues and the cysts did go away.
I pray for you and your baby that all will turn out well.
Happy to listen if you need to vent your fears...

My son had 4 cpc's, and after some research, I found that they are common, and usually disappear. At the first followup ultrasound, 2 had disappeared, and about a month after that, the other 2 had also disappeared. During all the time, we stayed positive, knowing there were no other abnormalities in the fetus. We referred to them as his superpowers, and I also would visualize them disappearing before I fell asleep. Bless you and your family!
