Chiari malformations are highly variable conditions that will affect every individual person differently. It is mostly seen that people are suffering from cerebellar tonsillar ectopia do not show any types of symptoms. Congenital causes of a syrinx include both Chiari I Malformation and Chiari II Malformation, Klippel-Feil Syndrome, Myelomeningocele, etc. Many authors use cerebellar tonsillar ectopia merely as a catch-all descriptive term for low-lying tonsils irrespective of the cause and thus including a spectrum from acquired tonsillar ectopia to changes in intracranial pressure 3-5. The degree of tonsillar descent is determined by first drawing a line from the basionto the opisthion (anterior margin to the posterior margin of the foramen magnum); this defines the plane of the foramen magnum. It, therefore, encompasses both minor asymptomatic tonsilar ectopia and Chiari I malformations . This relieves pressure and reduces compression on the brainstem, and may allow the cerebellar tonsils to move back to a more normal position. It appears below the temporal and occipital lobes and above the brainstem. Some individuals may not have any symptoms (asymptomatic) upon diagnosis as an incidental finding; others may have serious manifestations such as neurological deficits. In severe cases, doctors advice to go for surgery to correct the functional defects and to stop the further damage of the central nervous system. Abnormalities affecting the eyes can also affect individuals with a Chiari malformation including double vision (diplopia), abnormal sensitivity to light (photophobia), blurred vision, involuntary eye movements (nystagmus) and pain behind the eyes.

Basilar invagination occurs when the upper vertebrae are located upward, blocking the foramen magnum and thereby blocking the flow of cerebrospinal fluid. 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. We measured the degree of left and right tonsillar herniation in 42 pediatric patients with a symptomatic Chiari I malformation and made clinical/radiological correlations.

The disorder can potentially cause severe, life-threatening complications during infancy or childhood. The addition of Chiari malformation type 0 as a classification for Chiari malformations is controversial; some physicians believe that, for a diagnosis of a Chiari malformation, tonsillar herniation must be present.
