A member asked:

My fetus has choroid cyst on brain, doctor says not worry but how?

A doctor has provided 1 answer

Usually normal: Most babies with choroid plexus cysts in the brain are normal, and almost all cysts go away by the end of the second trimester. But cysts can also be a marker for a problem called trisomy 18, which means an extra chromosome 18 in every cell of a baby's body. A maternal fetal medicine doctor can do an ultrasound and look for any other sign of trisomy 18.
