To me it sounds like ischemic damage, which will result in punctate lesions in your brain. Depending upon the damage, it could cause vertigo, or it could be something completely different!
I have a lesion in my brainstem and cerebellum, and I had vertigo for three years.
Please ask the doctor about this question - we're not medical people around here, just folks with MS or looking for answers. That said, my very first instinct is this doesn't sound like MS to me. Good luck in getting the answers - it is horrible to hang out there and not have answers.
