Anyone have experience with a choroid plexus cyst?!

So I just had my 19 week ultrasound today.  I previously had genetic testing done which all came back completely normal. Today the doc said that the baby was measuring great and all of her organs looked great and she was moving a ton!  She then mentioned that she had a choroid plexus cyst on her brain. She said she hated that she even had to tell me because they see it a lot and it almost always turns out to be nothing if there was nothing else found on the ultrasound.  I am having extreme anxiety about this- anyone have any experience with this?!! Any input would be greatly appreciated!!
