Chiari Malformation

What is Chiari Malformation?

The Chiari Malformations are a group of disorders characterised by the cerebellar tonsils being herniated out the skull into the spinal canal. 


Diagnosis requires medical imaging. Magnetic Resonance Imaging (MRI) is the best way to diagnose Chiari. Computed Tomography (CT) scans can also pick up Chiari but can still some cases.


Chiari can be asymptomatic in some individuals. The most classic or "hallmark" symptom of Chiari malformation is the Chiari headache. There is a large list of symptoms someone with Chiari can also suffer from. 


Chiari may need either conservative or a surgical approach in treatment. Neither is a cure but many get good results.
