Isolated choroid plexus cysts?

Had an ultrasound today, the anatomy scan so we are just shy of 1/2 way there. I’m 19 weeks and saw my OB after my ultrasound. Doc said there were 2 choroid plexus cysts on her brain. There were absolutely NO other markers for any abnormalities in any other part of the ultrasound. I have a few options:

1. Wait it out til 28 weeks and see if they resolve on their own

2. Get a blood test and check for genetic abnormalities ($$$)

I like option 1 bc of the medical journals I’ve read about Isolated fetal choroid plexus cysts. I’m optimistic.

Has anyone had this on their scan? What did you do? How was the remainder of your pregnancy?
