Chiari Malformation

Diagnosis

Some symptoms of Chiari malformation may be subtle and can erroneously be attributed to similar symptoms of unrelated chronic conditions.

In addition to a thorough physical and neurologic examination, and an extensive patient history, the most definitive test used to diagnose Chiari malformation is magnetic resonance imaging (MRI) of the skull. Physicians can accurately view the cerebellum and surrounding structures and determine what form and to what extent the malformation has progressed.

MR imaging is also best for examining the spinal cord and the fluid surrounding it, giving physicians a good picture of the structural abnormalities that are causing the symptoms. For concerns about the bones surrounding the spinal cord, a CT scan or X-ray may be used to study bone tissue.
