18 week ultrasound

My 18 week ultrasound went well!!! Mostly everything is growing just as expected. There was one minor thing. The baby has a slight issue with the development of the choroid plexus area of the brain. It really does not mean anything but coincidentally, I researched this type of abnormality before my appointment. I found it interesting. This specific area of the brain is responsible for producing fluid. It has nothing to do with the "thinking" part of the brain. Bilateral choroid plexus cysts can be a soft-indicator of a chromosomal defect called Trisomy 18. The good news is that T18 is rare and in most cases the cysts are typically resolved in the 3rd trimester and the baby is born 100% normal and healthy.

My risk for a chromosomal defect was reduced to 1 in 10,000 at my 13 week ultrasound (the lowest it can be). The hands, feet, heart, spine, and placenta look completely typical. Therefore, the "heterogeneity" in the brain is just the tissue growing and changing. My baby does not have true cysts. I will not require another ultrasound because the doctor is confident that the abnormality is completely benign.

One more thing...it's a boy for sure!

Here are some videos of the appointment:
