Up until recently I never knew Choroid Plexus Cysts existed, or that a CPC could effect me/us.
That all changed a couple of days after Mary's ultrasound when she was notified that they saw a Choroid Plexus Cyst in our Baby Girl's brain. Apparently CPC's are fetal markers that a Chromosomal defect could be present. All Mary and I knew was that the Doctor found one, Mary's at a slightly higher risk, and we needed to schedule a level 2 ultrasound.
Keep in mind, Mary's Quad Check came back negative and the level 1 ultrasound looked great (coming from a layperson). When Mary called to tell me that they found a CPC, I was concerned to say the least.
Throughout all of Mary's pregnancies, I've refused to believe anything other then positive thoughts. We went through a similar situation with Isaac, we'll just have to do the same with our little girl to come.
I refused to do any research on CPC's and would just wait for the doctor to tell me what was going on with our girl.
Needless to say, as the ultrasound got closer, our worries grew.
Today, a day after the level 2 ultrasound I'm happy to say, my mental state is back to "normal". The CPC has gone away (which it will) and the level 2 ultrasound could not find any other fetal markers that would signal chromosomal abnormalities.
This does not mean that chromosomal abnormalities don't exist, this just means that we are at our inherent probability of a 99.5% chance that we will have a child without chromosomal abnormalities. Sure, we can get a 100% correct answer, but that would require and amniocentesis. That would then mean we would have a 0.5% chance of losing the baby, even if free of any chromosomal abnormalities.
We sat on the same Probability Pyramid with Isaac. Our mentality is the same now, as it was then. Why take a 0.5% risk when you plan to have the baby with our without a chromosomal defect.
As the doctor told us, we're "Logically Consistent".
What is the choroid plexus?
The choroid plexus refers to the area in the brain which makes the fluid that bathes the brain and spinal cord (cerebrospinal fluid). The choroid plexus is not an area of the brain involved in thinking.
The chance that a fetus with isolated choroid plexus cyst(s) has Trisomy 18 is felt to be about 1% or less if the rest of the ultrasound exam was normal. This means that there is a 99% or greater chance that the fetus does not have a chromosome abnormality. Choroid plexus cysts do not cause Trisomy 18: rather, they are a sign that the fetus may have a somewhat higher chance of having that condition.
