A member asked:
Slightly low lying cerebellar tonsils, probably secondary to tonsilar ectopia?
A doctor has provided 1 answer
Not tonsils: The cerebellar tonsils are not tonsils, just part of your cerebellum. Sometimes when patients are dizzy it is due to pressure from a portion of the cerebellum resting low in the skull, around the foramen magnum. If a radiologist noted the cerebellar tonsils ride a little low, they might mention it in a report. It would not be that uncommon of a finding on a normal MRI or ct of the brain.
