jaspen,
They picked up hydrocephalus during an U/S on my daughter Imogen, but it wasn't noticed until 36 weeks. i know of some people that they notice it on the 19 week U/S. My daughter is now nearly 7 months, she was delivered early by C Section due to concerns about the head size but it was found to be of normal size and didn't look abnormal as expected. At 8 weeks of age she had a VP shunt inserted and it was found that she also had thinning of the corpus collosum. At 12 weeks the shunt needed a revision due to the value dislodging from the tubing. It has been fine since. It was also discovered that there is a genetic problem, 6q deletion its called~ yet we are still waiting to see genetists to see what this means. She has had testing for many different things, puiturity, eyes, ears etc and has regular physio as she is a bit behind but the shunt has helped and decreased the fluid spaces on the brain and more brain matter has develop. She had been fine until a few days ago when she had a seizure and stopped breathing for about a minute, she pulled out of it fine and they are unsure what has caused this.. seems ok so far. They are going to do a EEG to check the brain waves in hope to find something. hope my daughter story has helped.
