Arnold-Chiari Malformation Support Group

Arnold-Chiari malformation, sometimes referred to as 'Chiari malformation' or ACM, is a congenital anomaly of the brain. Arnold-Chiari Malformation II occurs in almost all children born with both spina bifida and hydrocephalus, but ACM I is typically seen in children and adults without spina bifida.

Hello, I have a question. Is this anything to worry about?


Low lying cerebellar tonsils (9 mm below the foramen magnum) but with a
preserved rounded configuration most likely related to anatomic variance
rather than suggestive Chiari I malformation.


That is what the radiologist put on my mri results. My PCP says it's something I was born with but nothing to worry about. I have been diagnosed with fibromyalgia, neuropathy, myofascial pain syndrome, sciatica, yeast overgrowth syndrome, ADD, and plantar fasciitis. I have had headaches, migraines, facial numbness and tingling, ear pain, and eye pain since childhood. I had my first fibromyalgia flare in 2014 and now the doctors blame everything on that. I get to see a neurologist for the first time on October 19. I have been feeling like they missed something for a long while. Input would be greatly appreciated.
