Low-lying tonsils usually locate slightly below the base of the skull and measure less than 5 mm. Please note that NORD provides this information for the benefit of the rare disease community. Before surgery can be performed, the excessive fluid may need to be drained via shunt insertion. Brain growth causes pressure and crowding, which in turn pushes the cerebellar tonsils into the spinal canal. Fainting. April 30, 2021. she was diagnosed last month with a 4mm mild cerebellar tonsillar ectopia. This is in contrast to different types of CM, which involve the presence of other structural irregularities. Chiari malformations are highly variable conditions that will affect every individual person differently.

Chiari I malformations: clinical and radiologic reappraisal. Aiken AH, Hoots JA, Saindane AM et-al. With modern volumetric scanning and high-quality sagittal reformats relatively good views of the foramen magnum and tonsils can be achieved although the intrinsic lack of contrast (compared to MRI) makes accurate assessment difficult. Removal of part of the bony covering of the spinal canal (laminectomy) in order to provide more room for cerebrospinal fluid circulation and to remove scar tissue.

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. What does it mean? This kind of disease mainly develops at the time of fetal development. It may also be diagnosed after birth or in early infancy. It, therefore, encompasses both minor asymptomatic tonsilar ectopia and Chiari I malformations. Researchers have determined that the length of herniation (i.e., the amount of the cerebellar tonsils that protrudes through the foramen magnum) does not necessarily correspond to the severity of a Chiari malformation. 2004;16:1-7. http://thejns.org/doi/pdf/10.3171/foc.2004.16.2.6, Greenlee JDW, Donovan KA, Hasan DM, Menezes AH.

Importantly, features of intracranial hypertensionand craniospinal hypotension should be sought to ensure that cerebellar tonsillar ectopia is not secondary to abnormal intracranial pressure (and therefore not a true Chiari I malformation) 7,8. The cerebellum is at the lower back of your brain, and is mainly responsible for motor coordination. Additionally, treatments will depend on your age, overall health, type of CM, and other underlying conditions.
