However, depending on the type and severity, Chiari malformation can cause a number of problems. Before surgery can be performed, the excessive fluid may need to be drained via shunt insertion. These individuals often have syringomyelia despite the lack of cerebellar tonsil herniation. Chiari malformations are a group of complex brain abnormalities that affect the area in lower posterior skull where the brain and spinal cord connect. (2007). These include: Low-lying cerebellar tonsils, or CM-1 malformations, are the mildest forms of CMs. Individuals with hydrocephalus may be treated by the implantation of a tube (shunt) to drain excessive cerebrospinal fluid away from the skull and brain to another part of the body where the CSF can be absorbed. There are four types of Chiari malformations.
