What is the inferior displacement of the cerebellar tonsils?

Inferior displacement of the cerebellar tonsils refers to the downward herniation of the cerebellar tonsils through the foramen magnum, the opening at the base of the skull. This condition is often associated with Chiari malformation, where structural abnormalities in the brain lead to increased pressure and displacement. Symptoms can include headaches, neck pain, balance issues, and neurological deficits. Treatment may involve surgical intervention to relieve pressure and restore normal anatomy.
