Hi everyone. I had my 20 week ultrasound last week. My doctor called the other day and said they found a choloris plexus cyst in the brain and that I have to go for level two ultrasound. He said not to worry but ofcourse I'm freaking out. The cyst could either disappear or it could mean my baby boy has trisomy 18 / downsyndrome. All my blood work and other tests up to this point have been fine and the baby looked good at ultrasound so I'm trying not to panic. I go tomorrow for the level two ultrasound and then will know more. Has anyone else had this happen??
