Can any doc tell me what does low lying cerebellar tonsils mean?

Arnold Chiari: Low lying cerebellar tonsils refer to the presence of cerebellar tissue below the foramen magnum. Usually referred to as Arnold Chiari Type I, which are in general asymptomatic and seen as an incidental finding on MRI of the brain. Best to check with your doctor for certain.
