One of my friends just had brain surgery for it last week. She went for years and years with doctors not knowing what was wrong with her. She suffered from headaches, horrible back pain, etc. Basically, your brain kind of spills over into your spinal column, causing lots of issues. I don't know too much more than that, but I know that you can potentially die from it. She feels much better since having her surgery and it's only been a week. I'll pray for that little girl.
