(Left) Sagittal T2-weighted image of the spine; (Right) Sagittal T1 weighed image of the brain. Note in the Chiari malformation that the brainstem and cerebellar tonsils descend below the foramen magnum. In this case, the cerebellum and caudal brainstem descended 25 mm below the foramen magnum. In addition, there is a syrinx in the high cervical cord. There are various types of Chiari malformations. In Type I, the malformation is limited to descent of the brainstem and cerebellum into the spinal canal. Other types may be associated with midbrain malformations, aqueductal stenosis, and myelomeningocele.
