Choroid Plexus Cysts


Dear Midwife,
I am 20 weeks pregnant. on my 20-week scan they noted bilateral choroid plexus cysts on the baby's brain. Otherwise the baby is healthy. they told me not to worry and didn't take any further action. however, I want to meet up again for them to discuss it with me since I am an emotional wreck since they told us.

Can you reassure me that I don't have to worry too much?

I am 25 and this is my first baby.


In most cases, these cysts are considered a variation of normal, since they do not affect the baby in any way we can measure. They seem to be benign and don't bother anything. Personally, I am inclined not to even tell parents about them, as some parents can't stop worrying about them. It sounds like your baby has the benign variation, which is the majority, so not to worry!
