Chiari Malformations

Chiari ("kee-are-ee") malformation is a disorder of the brain where the cerebellum is herniated through the foramen magnum and into the spinal canal. The foramen magnum is the hole in your skull that the brainstem and spinal cord exit.

Our UW Medicine Chiari Malformation Clinic is headed by Richard G. Ellenbogen, MD, FACS, Professor and Chairman UW Neurological Surgery, Chief of Neurosurgery at Harborview Medical Center, and Chief of Pediatric Neurosurgery at the Seattle Children's Hospital and Regional Medical Center in Seattle, Washington.

Adults with Chiari malformations are treated at Harborview and UW Medical Center while children are treated at Seattle Children’s.  Both locations utilize world-class doctors, nurses, patient care coordinators and facilities to provide exceptional treatment for this condition.
