Choroid plexus cyst

Day
I went for my anatomy scan at 19 weeks and my doctor said they found a cyst called Choroid plexus cyst in my sons brain. She said not to be concerned as this happens often and usually disappears in the third trimester. Otherwise everything else was perfectly fine. Has anyone else had this happen to their baby? Im worried even though my doctor said not to worry but I would just love to hear from other mommies if this has happened to them in prior pregnancies or current. Thank you.
