What are the tests for chiari malformation?

Head/ Cervical MRI: Chiari malformation is best diagnosed with a head MRI without contrast to assess for the abnormal tonsil position and determine whether hydrocephalus, or water on the brain, is present also. A cervical MRI without contrast can assess for a problem called a syrinx, or a fluid cavity in the center of the spinal cord. A lumbar MRI without contrast can also exclude a tethered cord causing numb legs. ...Read more

How is the chiari malformation diagnosed and evaluated?

Clinical exam, MRI: A thorough evaluation and clinical exam can assess for symptoms of chiari. If there is suspicion, an MRI of the cranio-cervical junction will confirm the diagnosis. Dynamic MRI with cine can show the lack of cerebrospinal fluid pulsations. At times, chiari is being identified on MRI in a patient with no symptoms. A neurosurgeon should be consulted regarding any need of treatment. ...Read more
