My MRI was crystal clear MS... said periventricular (I believe) area of the brain, and another area that I don't recall... but the lesions and locations were typical of those in MS, however when my regular doctor saw the MRI, before I saw the neuro, they said the lesions could be from other causes.

Which is why MS can't be diagnosed based on positive MRI results alone.

It's good that my MRI was so telling, and my lumbar puncture came back with o-bands, because my symptoms were, for the most part, not hallmark MS symptoms, but vague neurological symptoms that can show in many mimic diseases.
