Simplified Explanation

Basilar Invagination is where the second vertebrae in the spine is higher than it should be. As a result, the opening at the base of the skull is narrower than it should be and can partially close off. This can potentially impede the flow of cerebrospinal fluid (CSF) and/or put pressure on the brain stem or spinal cord, causing neurological problems.

Treatment

Depends on the severity. If there is no evidence of neurological effects or pressure on the brain stem or spinal cord, no treatment may be necessary. However, if there are signs of issues, surgery is necessary.
