When I get my surgical reports I see these things, too. I'm not diagnosed MS, but they won't rule it out yet. However, they tell me my tests are normal and there are always little things in them. One doctor told me they are nothing to worry about and most people have them in their bodies. Like I have a nodule in my left lung that is stable one report said. A cyst on a kidney. 2 hemangiomas? in my liver. No one ever mentions it. I have to read in my reports for myself. That's why I always get a copy of my reports. You never know if they things will add up to something later. Especially when you have mystery symptoms like mine.
