Okay, it might be time to seek a new neuro, I had nearly the same results from my contrasted mri and lumbar puncture, and my neuro had no problem at all calling the duck a duck, that is to say I got diagnosed with MS. I think it was 5 bands in the LP but all that did was kind of cement it. i think you need at least 3, which you have. And as far as the mri went there were only 3 lesions present and the cervical spine was clear.

Granted, I don't know exactly where the 'white matter' is on your films, but I would definitely ask for a second opinion.
