We hadn’t posted anything about this because we really felt that everything was going to be ok and didn’t want to cause any unnecessary worry. When we had our ultrasound last week, for the most part everything looked just fine. They told us at the end though (and were able to show us) that they did find two Choroid Plexus Cysts in his brain. The Choroid Plexus is the area that makes cerebrospinal fluid (thank you google). The cysts can be likened to a blister and are not considered a brain abnormality. These appear in 1-2% of babies, and typically go away and they themselves don’t seem to be a problem.
However, they are also associated with Trisomy 18. If the cysts are all that are present it doesn’t seem to increase any risk or anything. Luckily, the ultrasound tech was very quick to tell us that from what she saw everything looked just fine. One in specific that she mentioned was that his hands were open, which I guess closed hands can be another indicator.
So with that, we were sent for a Level 2 ultrasound and appt with maternal fetal medicine today. They were being cautious and wanted to do a more in depth look to make sure there weren’t other indicators. While we really were feeling confident going into it, I didn’t sleep much last night and was a basket case this morning before the appt. Luckily, everything looked great! They spent a long time really looking at everything and there were no other markers of Trisomy 18. The cysts will most likely disappear by the third trimester.
And this baby looks to be a big one, just like his older brother. He’s measuring 8-10 days ahead, just like Luke was at this point. Even though they say that doesn’t necessarily indicate size at birth, Luke came out at 9lbs 3oz with a 98% head, days early. I think I just grow big babies. :)
