Welcome to the NeuroTalk Support Groups!
You mention positive EBV. I take that to mean Epstein Barr Virus? My daughter had/has that. Affected her greatly.
I can't comment on the radiology report I'm sorry. Sounds as if you've been given the run-around by your treating doctors.
Here's the link to the MS Forum here. They're a really great group of people.
I'm sure if you repost your message over there as well, you may get more responses.
