No need to be sorry guys.
My son had such a rare form of meningitis when he was born that his case wrote the book on how to treat it.
It left him with brain damage in his right occipital lobe which is causing epilepsy, loss of right left side vision and a mild developmental delay which all thins considered is really good given what he went through.
He had the PET scan completely healthy as a planning stage to bisect the damaged occipital lobe and cure his epilepsy. They use the PET to see the dead regions so they can plan where to cut.
