Choroid plexus cysts.

So at my 20 weeks anatomy scan they said my baby had cysts in the choroid plexus part of her brain. they didn’t find any other abnormalities and they told me they usually go away with growing. but it still worries me. did anyone else’s baby ever have these? and did they go away? i’m 26 weeks now and go back to the doctor next monday and i’m really scared they’ll still be there.
