However, you have hydrocephalus or a syrinx, some intervention may be necessary. Best advice: see a neurosurgeon to go over your MRI & provide a good physical exam.

I saw a doctor who diagnosed chiari malformation. Now he wants to do treatment. I suspect he is churning. What is significance of the condition?

I'm not sure quite what you mean by churning but if you're uncomfortable with your neurosurgeon, please seek another opinion. Remember that we are here to help you and you should feel that from your surgeon. ...Read more

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
