I can only interpret on the basis of what you write, and have not seen the scan, but if interpreted correctly
the findings are suggestive of MS, but not diagnostic - to make the diagnosis of MS there has to be demonstration of demyelination (or damage to the myelin insulating sheath that helps nerves to work properly) in more than one area and at more than one point in time (seperated by at least several weeks)
So your neurologist will need to tie things together with your history and your current and previous MRI scan
Other possibilites could exist such as ADEM (acute deyemlinating encephalomyelitis, which is really a single non-recurrent form of demyelination, not likely if you MRI was abnormal in the past), sarcoid, vasculitis, Behcets, ministrokes from high blood pressure, migraine
but from the description, the abnormalities are suggestive of lesions typical of MS - do not be disheartened though as you still need to see your neurologists and get a full interpretation of the results, and what should be an answer and effective treatment for your symptoms
Good luck
Thank you very much for your response - I appreciate it!
