Hi there, i'm JJ the community leader of the MS community and just came across your question...
Something has definitely been going on but its not necessarily a neurological condition like MS though, diagnosing MS is still complicated even after decades of tweeking the MS Mcdonald diagnostic criteria and rarely dx'd on the results of just 1 MRI. Did you also have a spinal MRI and i'm asking because MS commonly causes brain and or spinal cord lesions and depending on your symptoms and or clinical signs of neurological abnormality, its possible for a spinal MRI will add to your full diagnostic picture.
Hope that helps......JJ
