Hello from Greece
I am Kostas Tsirgiannis and recently (April 2012), my brother Dimitris had a brain surgery in INI Hannover http //www.ini-hannover.de/ .
The operation was succesful although now he has major kinetic problems, which will be cured with physiotherapy as the time passes by, according to the doctors.
You can contact them and send them your MRI’s and they respond quickly.
With best wishes
