Anyone else have a choroid plexus cyst found on baby's brain during ultrasound? We learned that our baby has one yesterday. It could possibly be a marker for trisomy 18 but baby didn't show any other markers. From reading up on it a lot of people say the cyst went away by the next ultrasound and everything was alright in the end. Trying to stay positive until our next scan April 18th. Please send extra prayers our way.
