(((hugs))). It's never a good idea to get the MRI report back before you see the specialist. They can insinuate very scary possibilities.
Basically, the radiologist has suggested that the particular lesions noted "could" be suggestive of a demyelinating process (such as ms). This is because of the specific location of the lesions found on your scan.
However, brain lesions can be caused by a myriad of conditions, including migraine, autoimmune, smoking, lupus, Lyme, and many more. Even spinal lesions can have other causes.
Why were you sent for an mri in the first place?
Unfortunately, there's not much an online community can do to help you. It's going to take a conversation with your neurologist to sort out what is going on. Often if the lesions are tiny, they will be termed "non-specific" by a neurologist, even if the radiologist considers them potentially important.
Big breath. When do you see a neurologist for follow up?
