I did have a second MRI done with contrast, and he said it was just to prove that it wasn't a brain tumor. Remember, this was before I was diagnosed with MS. He told me over the phone that the results that came back proved it wasn't a brain tumor. Later on in another appointment, he said that even though it doesn't prove it wasn't a brain tumor, doesn't leave out the possiblity that it is. So basically he doesn't know why the white spot is there?? Which is why he waiting until July 2nd to get another MRI done on my brain to see if there is anything that has happened?
