Right ventricle of baby's brain - 10 mm

[AMS04]

Hello - I just had my 20 week ultrasound.  My doctor said everything looked perfect except for one "minor" concern.  The right ventricle in the baby's brain is measuring 10 mm, which is still within the "normal" range, but since it's at the top end of the normal range, my OB wants me to get a level 2 u/s and talk to a high-risk OB.  She said they are just being careful and want to make sure the width of the ventricle does not increase, as anything over 10 mm could be a sign of fluid building up on the brain.  We are trying to remain calm and remind ourselves that our baby's ventricle is still normal, but thinking about what it could be is terrifying.  I should also tell you that we have had genetic testing (for Downs Syndrome and other chromosomal abnormalities) performed already, and everything was normal.  Nothing else out of the ordinary was found on the u/s, either.  Has anyone had a similar experience?  I'd appreciate any advice/thoughts.  Thank you!!

i'm sorry i haven't had this experience to be of more help. but i am currently in a high risk pregnancy due to bleeding in and under the amniotic sac. at 3 months pregnant, unfortunately nothing can be done about this and it's just a case of wait and see. but the lady who did my scan did say something that's helped me deal with it a little better...' nothing can be done about this bleed so you may as well just forget it's there' so every time i start to worry i occupy my mind with something else
