Yes, I've had several MRI's of the brain and spine with and without contrast over the years. It seems many people with CFS/ME have symptoms very much like MS.
I forgot to mention that even though I haven't been diagnosed with ME or MS, I've had many other neurological symptoms that people with ME and MS have : optic neuritis, numbness in areas such as the lips and tongue, to hands and feet, liver area, and so on.
I would guess that it's the types of pathogens, their location, their toxic metabolites, and the body's reaction that makes the symptoms vary.
There have been various microbes found in the CSF of both MS and ME patients.
I guess that's also why some with MS or ME respond to corticosteroids, and some don't.
