I just read your post on another thread and I think it makes a little more sense now. If you had one MRI and 5 lesions and only one clinical episode of MS type symptoms, your neurologist may be looking for changes over time to confirm that things are progressing. If they are strictly looking at the MRI evidence and saying they need 7 lesions, it sounds like they are using the McDonald Criteria and looking for new lesions separated from the original 5 by more than 6 months. I would have thought that with a history of clinical symptoms over time and the 5 lesions on MRI, the doc would give a diagnosis, but it sounds like they want to see it on the MRI before they give it. Also, be aware that radiologists saying the lesions are "stable" doesn't mean there aren't more. I had a report of "no change to high signal intensity areas in white matter" when my lesion count went from 2 to 7, and resulted in me getting an MS diagnosis. It is best to let your neurologist look at the scan and go from there. Again, Good Luck!
