Jan, I really am not sure why he called but I am so happy he did. I think the personal interaction I had with the radiology center might have had something to do with it but I'm not sure. The woman who collected my MRIs and sorted them (they were in a state of disarray) remembered me and was sooo nice. She knew a little bit of the story behind the story regarding my quandry. Or, perhaps that it may have been that these old MRIs were delivered so long after the fact and he thought perhaps there was a reason.

I also think that something may have puzzled him and that he was trying to learn himself and that any information I could give him might be helpful in creating the addendum. He did not try to dx me and made it clear that he was a radiologist and not a pathologist. He gave both my doctors a big thumbs up -- this was comforting to hear because of my relationship with my MS specialist. I know he's smart but he just doesn't make me feel like he cares. When I visit him I feel like a statistic sitting in a chair. Completely a different experience than what happens when I visit my neuro-ophthalmologist. A lot of what I learned about MS early on was from her.

Re: the white matter lesions, I know that they can be caused by a number of things, not limited to but including smoking, migraines, small vessel disease and just normal aging. My friend's girlfriend is a neurologist specializing in migraines and she told me that MS lesions tend to be DEEP in the white matter but she HAS seen cases atypical of both conditions that can be confusing. And of course, there are also other conditions that can cause lesions that look just like MS lesions.
