If this is an OLD MRI, it sounds like you need an new one! I would ask your doctor to run a NEW MRI and see what it looks like. Taking an old MRI to a Neuro isn't going to do much good. You need a new one.
See if you can get your doc to order a new one and take that to a Neurosurgeon. You'll get better answers. Let me know, will you please? I'd really like to know. God bless! Hugs, Lee
