Dear Mr. Fenton:
Sorry to hear about your "to be newborn". There are a couple of things to think about, first is how large are the ventricles? If they are only slightly enlarged, then I think there is likely nothing serious going on. Second, if your ultrasound is of the highest quality then this might be an overcall, it depends alot on the person who is reading the ultrasound. Third, watching whether there is some sort of obstruction or not is important (very doubtful). Fourth, I would agree that if the head continues to grow (therefore the brain is growing) then there is less to worry about. But, since I haven't seen the ultrasound it is difficult to tell you the outcome, even if I did, it would still be difficult. I think this should tell you that infants brains are very plastic (meaning that they can overcome alot of insults) and develop normally inspite of insults.
I would not worry about the IgG titer. This just means that your wife has been exposed in the past (as most of us have been). This does not mean that she is actively infected and should worry about prenatal affects. The IgM is more critical in determining a recent infection.
I hope this helps alittle.
Sincerely,
CCF Neuro MD
