So sorry to hear about this. Happy he is doing well. Just out of curiosity, was he infected with Toxoplasmosis, CMV or Rubella in utero?
the doctors ruled out infection and x-linked hydrocephalus. the neurologist said that there could be some genetic relation to the condition, but it was probably rare and they wouldnt be able to recognize the target sequence. They just diagnosed it as aqueductal stenosis of the third ventricle.
Man, what a great story. That little guy obviously has 2 amazing parents. Congrats and thanks for sharing!
