Can this be chiari ?

Hello everyone,

So I uploaded a picture of my mri and ct on my profile,

My cerebellum is at the base of the foramen magnum,

Is that dangerous ?

Any recommendations ?  

I have headaches not any other symptoms, can this be the cause ?

My opinion is that this picture was taken while I was lying down, if I stand up the cerebellum could move further down by the effect of gravity, is that possible ?

Any help is so much appreciated
Thanks !

Hi...your cerebellum is not the issue but the cerebral tonsils,,,,yours looks like it is right at the FM and not herniated....and as you pointed out you were supine and may not show how gravity effects it when upright. Chiari is a malformation of the skull and not being a medical professional I can not say if you have Chiari or not.....but your tonsils do not look herniated from these films.

It is highly  possible to have symptoms even without herniation if the tonsils plug up and block CSF flow.

A CINE MRI will record CSF flow in real time to see if it is obstructed....most times this is done supine as well and if there is a blockage it will show regardless if you are upright for the MRI.
