If not Chiari Malformation than what???

[tcampo]

Hi, I recently had an MRI due to the fact that I have been experiencing a lot of nerve pain in my legs, back etc. as well as migraines and hearing loss in both ears and back and neck pain that is so bad MOST DAYS that I dont know what to do, and I was at my wits end.  They were trying to rule out MS and what they found my neurologist said it looks like chiari malformation only in reverse and he has never seen it that way so he needed to do some research of his own to figure out what it is, in the mean time I am still being sent for a battery of tests. What  the impression was of the radiologist was Mild ventral cervicomedullary compression in conjunction with degenerative changes of the atlantodental joint.  The report reads as follows: There is a Mild protrusion of the cerebellar tonsils through the foramen magnum. There is mild hpertrophy of the atlantodental joint with mild compression of the ventral cervicomedullary junction. Now have you or anyone you know that is familiar with Chiari Malformation heard of it being like this and if not, what can cause protrusion of the cerebellar tonsils through the foramen magnum? As well as hypertrophy of the atlantodental joint with mild compression of the ventral cervicomedullary junction? If you have any answers, or know someone who would be able to help me I would be tremendously grateful.  The more answers I have the better. I cant find any of this in my own medical books and am running into dead ends online so not sure where else to turn. Again Thanks and have a great Day!
Sincerely,
Taira Campo

Thank you for your comment but if you had read my question in full I did see my Neurosurgeon/ Neurologist. My case presents as Chiari Malformation but in reverse as I stated He has never seen it like that and was going to do some more research. SO I was trying to get more info from fellow doctors in the same field maybe they would know what it was if it wasn't Chiari or would have some better insight into my situation based on the way it is being presented. I am a researcher at heart and just wanted to know what I needed to look into since I wasn't finding anything under the impression given by the radiologist. So Thank You but your Answer really did not help me at this time. HAVE A NICE DAY.

The best advice I can give to you is get a copy of the actual scan and make an appointment to see a neurosugeon.  They have significant experience with Chiari malformations.  They do show up on routine MRI scans and most do not cause any dangerous problems.  Most do not require surgery but you need to have a physical exam to correlate any findings with the mri.
