I've just been going through all the MRI's I've ever had, and came across this I had forgotten about, because my doctor, at the time, said it was nothing to worry about, and was common. I looked it up on the net, and what came up was Arnold-Chiari Malformation. I had this MRI done before I was diagnosed with FM. In fact it told me I have DDD at C5-C6, and C6-C7. On this report from the radiologist, he recommended that I get further neurologic consultation. Of course I didn't, because my primary doc said it was nothing. So, anybody out there with FM or any other condition on these boards know they have this? If so, wonder if it's related to FM.
