Arnold-Chiari malformation type 1 is a structural defect involving the cerebellum, the part of the brain that controls balance. It involves the extension of the lower part of the cerebellum into the foramen magnum, without involving the brainstem. Normally, only the spinal cord passes through this opening. This malformation is the most common type of Arnold-Chiari malformations and may not cause any symptoms.[1] Click here to view a diagram of the brain.
