Overview
The prevalence of Arnold Chiari malformation is unknown since most of the cases are accidentally found. The mortality rate of Arnold Chiari malformation depends on the subtype but type 3 has the highest mortality rate as a result of respiratory failure in infancy. Arnold Chiari malformation commonly affects adolescence and adulthood, but also has been seen in younger children. There is no racial predilection to Arnold Chiari malformation.
