Oh, I should mention that when I had my brain MRI, they never found MRI evidence that I had any lesions on my optic nerve.

When I had another (two) MRI's four months later, they did find a lesion or two on my spine. (had two MRI's then because the first MRI they couldnt get any contrast in because the nurse at my doctor's office destroyed my one good vein the day before the MRI)

When I had the 6th cranial nerve palsy in June and july, I pretty much refused the MRI because all it would do is give me a higher medical bill, we could already tell that I had a lesion on the nerve, we didnt need to take pictures to confirm it. Yay that my neuro is pretty much old school and can tell you where the lesion is by your symptoms and doesnt feel the need to confirm it with the MRI.
