20 week scan/cyst on baby’s brain

SL

Hi ladies!

We just had our 20 week scan this morning and sonographer found small cysts on the babies brain. She stated that this is very common and asked if we had the first trimester scan done which I advised yes and everything came back normal. She stated with everything being normal with the blood work during the first trimester scan and everything else about baby being completely normal she advised us not to worry as it would most likely go away on its own, she something she likes to mention to her patients. Just curious if any other mamas had experienced this? TIA!
