Maura was diagnosed with Chiari I in 2007 at age 6 via a traditional horizontal MRI. “I had a decompression shortly after diagnosis and had significant relief for 8 months. After that symptoms returned but slightly differently, so I had a full decompression. Turns out it was craniocervical instability that caused the symptoms to return after the first decompression so the second decompression was ineffective.”
Chiari Malformations are structural defects located at the in the base of the skull where the spine meets it. These structural defects can cause the brain to sag into the spinal canal, causing herniation of a portion of the cerebellum, cerebellar tonsils and/or the fourth ventricle. Depending on the severity, there are a variety of symptoms and complications that come with Chiari Malformation.
