--you may be able to get more opinions on spinal cysts or other growths in the spine causing neural symptoms at some of the forums here that deal with that more specifically:

I would think that anything that causes compression in the spine or the adjacent nerve roots could cause neural symptoms, depending on where the pressure was, but your symptoms do sound a little more global than one would expect in cases like that (especially the optical ones). Given your family history, the doctors should be monitoring you closely for signs of MS or other demyelinating diseases of the central nervous system; sometimes the original signs of this are rather ambiguous, and there's a lot of controversy in the MS field about "probable" vs. "definitive" diagnosis based on episodes and associated imaging findings.
