Cyst on babies head.

Got to see my little Liam Ash yesterday at 19 weeks exactly and he weighs 10 oz. OB said baby looks great and healthy but she noticed a 3 mm cyst on his head. She said these cyst are usually benign and resolve themselves and most doctors don't tell the patients about these cyst because nothing bad comes from it. At my next appointment when I have my glucose test in a month I will be having another US done to monitor the cyst. Any other mothers been told about cysts on there babies?
