Warning Signs Of Chiari Malformation

In Chiari malformation, a patient's skull may be misshapen or smaller than normal, compressing the cerebellum. The compression causes parts of the brain to protrude into the spinal canal, obstructing signals from the brain to the body. Most cases are congenital and result from genetic mutations, lack of nutrients during pregnancy, infection during pregnancy, or chemical exposure during pregnancy. However, an adult may develop Chiari malformation when infection or an accident results in spinal fluid drainage.
