"Yes, you remember correctly. Typically, MS lesions are found deep in the subcortical white matter and around the ventricles, though there can be lesions elsewhere. In migraine, the lesions are often not as deep, though there are migraine patients who have MRI's that look like patients with MS (this is a minority of migraine patients). When I meet a patient who has migraine and has an MRI with multiple suspicious looking lesions, I usually either refer them to ensure nothing else is going on or repeat the study to ensure stability. There are other causes of deep white matter lesions. Hope that answers your question."

That is very interesting and I really appreciate you asking your friend.
I have one MRI report that states that my particular lesions are often seen in MS patients. I have another MRI report that says they are suspicious for demyelinating disease specifically MS, but to also consider Lyme and small vessel disease. Then there are the reports that just state that there are multiple lesions in the deep white matter.
I have had one neuro (my 1st neuro) flat out state that my lesions are no big deal - called them UBO's and said they could be caused by the migraines I don't have. Both MS specialists I have seen consider them to be demyelinating but the sticking point seems to be a lack of the periventricular ones. So, I kind of think your friend cleared up one thing for me when she mentioned that part.
It seems that I have one part of the puzzle. The neuros seem to be confused about the lesions appearing in the deep white matter before any evidence of the periventricular ones.
One of them said something one time to the effect that they usually appear in the periventricular area first because of the blood brain barrier issue. I'm sorry I can't seem to explain that better. I can't come up with the words today. It was just something along the lines of the area in closest proximity to the ventricles being more easily attacked???:confused:
The first neuro I had (UBO boy) was totally convinced I had MS until he saw the MRI results. Based on my neuro exam, he said he thought he would find my brain loaded with MS plaques. What he found was a bunch of smaller deeper lesions. I am pretty convinced that if I had periventricular lesions right from the start, I would have had a dx back in 2004. Luckily for me, he was still convinced something was really wrong and he sent me onto MS specialist #1.
My current dx is CNS Demyelinating Disease because my neuro won't quite call it MS because of my atypical lesions. He says it is "atypical MS" and treats me with IVSM (we used to do pulse IVSM before my bones started thinning) and treats my sx with the same types of meds as MS patients (i.e. Baclofen, Provigil, etc.) but isn't willing to use any of the DMD's or Tysabri on me because they were made for typical MS patients with typical MS lesions and he isn't sure there would be any benefit for me.
The one thing he has stated quite clearly is that my lesions are definitely demyelinating and they are not normal in someone my age. He told one of the med students in with us one time that white matter lesions in a younger person are never normal, but that some doctors will just call them "normal" when they don't have a clear answer for a patient. He made it pretty clear that he doesn't think that is appropriate.
I just think this whole subject is kind of fascinating and reminds us that there is so much they don't really know and understand about this disease and even about lesion formation and location.
