Chiari malformations are developmental or structural defects in the base of the skull and cerebellum, the part of the brain responsible for balance. Most people suffering from Chiari malformation experience vague or minimal symptoms. In some cases, no symptoms may be present. Most Chiari malformations are detected when tests are performed for unrelated disorders. Depending on the type and severity, Chiari malformation can cause a number of problems.
Chiari Malformation Type I
People with Chiari malformation type I can experience the following symptoms:
- Dizziness
- Muscle weakness
- Numbness
- Vision problems
- Headaches
- Problems with balance and coordination
Chiari Malformation Type II
In Chiari malformation type II, more tissue extends into the spinal canal and the symptoms can include those related to myelomeningocele, a condition in which the backbone and the spinal canal haven’t closed properly before birth. Chiari Malformation Type II symptoms are as follows:
- Changes in breathing pattern
- Swallowing problems, such as gagging
- Numbness
- Quick downward eye movements
- Weakness in arms
- Severe headache
Chiari Malformation Type III
In the more severe Chiari malformation type III, a portion of the lower back part of the brain (cerebellum) or the brain stem extends through an abnormal opening in the back of the skull. This is often diagnosed at birth or by an ultrasound during pregnancy.
Depending on severity and diagnosis, treatment options vary. If you have been diagnosed with a Chiari Malformation, surgery may be helpful.
