Hay, nakita ko yan sa ultrasound ko too during pregnancy at honestly nakakagulat talaga, pero sabi ng OB ko it's actually pretty common and usually resolves on its own, the choroid plexus is just part ng brain na nag-produce ng fluid, at minsan lang may cyst or extra tissue doon na makikita sa scan. Best thing to do is discuss it directly with your OB kasi sila ang makakapagsabi kung kailangan ng follow-up ultrasound or kung normal lang talaga siya based sa baby's age and other factors sa scan, don't stress too much muna, maraming cases na okay lang ang nagiging outcome!
