Hi wishing well....I can't see the MRI, but if you are doubtful please make an appt. with your neurolgist and tell them at the time that you want the MRI read by the doctor himself. CD's make it so easy today, compared to the original huge copies, and you should have a copy of each one of these in your file at all times. The hospitals are very accommodating about providing them, the dept. they're done in, etc. You may be charged a small fee, that depends upon the facility, but it's worth it to always have a copy AND a radiology report. e.g. I have no idea where my shunt comes out. Yes, it makes a huge difference when faced with other surgeries, but the Dr. has left the city and even my neurologist doesn't have that report. Do you see what I'm getting at?
When one has Arnold-Chiari chances are good for Syringomyelia. Surgery today is much, much easier and is usually done at the same time as the Chiari surgery which, while sounding horrible, was actually much easier than the cord surgery I had. Things progress & that's wonderful, now take advantage of them. Personally, I meditate when I'm in the MRI. Just make certain that you have earplugs b/c it can get pretty noisy in there. I went from the earliest machines to the ones used today and they're so much better. Plus the pictures are much clearer making it easier for the neurologist and the neurosurgeon.
Don't over-worry about what may be going on. You'll catch anything now. Birth defects are funny things...if you have one chances are great that you have more than that. I'm grateful that it was found before more damage was done. In those days, I was extremely fortunate, and I know it.
An organization known as American Syringomyelia Alliance Project (ASAP....Longview, TX) will help you with this. You'll find a lot of information, including the closest neurosurgeon in your locale (who can really operate on this...it's not the hardest of surgeries, but you do want someone who has dealt with it). I'm fortunate in that I was able to track down a neurosurgeon from S. Africa who had operated on plenty of cases there. A foreign Dr. will often recognize both SM and ACM before an American Dr. Make certain your Dr. speaks good English, as that makes a huge difference in how you understand each other. The neurologist are considered the top of the totem pole in the medical world, they then descend to neurosurgeon, etc., from there. To have a good neurologist is worth his/her weight in gold...they're generally the best. You'll find ASAP on Facebook. I was a very early member who took on talking to people on the phone, helping them with insurance, and doing anything I could. As the world grew larger, I took on a lot of the phone calls from people who phoned in from around the world. Trust me, if you ever think our medicine is bad, do that for awhile and you'll understand what the word "bad" means. Which isn't to say that you should put up with an arrogant, uncaring Dr. Find someone else and one more tip: If you don't want to sit in a neurosurgeon's office all day, make your appt. for first thing in the a.m. Yes, many of them begin 5:30 a.m. or so, but it's so worth it to get in and out. Besides, traffic is better, too.
Good luck. I'm here if you need anything else or want a hand to hold. Don't assume that you have these things, but be diligent in ruling them out. Yours, Lenora.
