Chiari malformation (CIM) presents an interesting pathology, affecting both children and adults. It is described as a downward displacement of the cerebellar tonsils through the foramen magnum. This downward displacement of the cerebellar tonsils (more than 5-7mm below the foramen magnum) is the primary cause of signs and symptoms observed. This herniation can be a result of congenital or acquired malformations. There are several theories yet to be proven behind the development of congenital CIM. These include aetiologies such as small posterior fossa, hydrodynamic insults, hindbrain dysgenesis, underdevelopment of the basiocciput, lack of ventricular distention, and genetic causes. Aetiology for acquired CIM may include trauma, craniosynostosis or intracranial mass lesions just to name a few.
