Mick, I was wondering....when reviewing the many MRI scans that you've had to take, did your DR ever tell you that your brain "has fallen slightly" into the brain stem? My son has the same story as yours, except he is only 10 now...so 1 shunt, 1 revision, and 5 years of good life. Thanks to God and a great DR. But this is what I am dealing with right now..The doc says its not a big deal, not to worry. But that we will keep an eye....
