Chiari Malformations

What are Chiari Malformations?

A Chiari malformation (kee-AH-ree mal-for-MAY-shun), is a condition in which brain tissue extends into the spinal canal. It occurs when part of the skull is abnormally small, pressing on the brain and forcing it downward. The malformation is named after Austrian pathologist Hans Chiari.
