Chiari malformation type I occurs when the part of the skull housing the cerebellum is mishapen or too small leading to the tissue in the lower part of the cerebellum to move in to the spinal cord.

Chiari malformation type II is typically linked with myelomeningocele, a form of spina bifida, in which the backbone and the spinal canal haven’t closed properly before birth.

Most sufferers of chiari malformation have vague or no symptoms altogether. Commonly chiari malformation is detected only when tests are performed for other disorders. However, depending on the type and severity, chiari malformation can a variety of problems.

To diagnose chiari malformation, your Newport Beach orthopaedic surgeon, Dr. Todd Peters will perform a complete and thorough physical examination as well as a medical history check. He may also request X-Rays, MRIs, and CT scans to better assess your case.

X-Rays – A type of quick imaging process using electromagnectic waves to better show Dr. Peters bones of the body to pinpoint possible sources of pain.

Magnetic Resonance Imaging (MRI) – This type of imaging uses radiology to show Dr. Peters the soft tissues of the body like muscles, disks, nerves, and the spinal cord.

Computerized tomography (CT) – CT scans are X-ray scans taken from various angles to create a cross-section of bones and soft tissues of the body.

If sever enough, Dr. Peters may also recommend surgery to alleviate the pressure and regulate the progression of chiari malformation.
