I'm supposing you are referring to a Chiari malformation. If that's the diagnosis and it's causing symptoms then the only treatment is surgery. While like every surgical procedure it has its risks, the prognosis is pretty good, especially if on neurological exam she has no other neurological deficits.

Hi, I had gone through your question and understand your concerns. That condition is probably Arnold-Chiari type I malformation. Your daughter needs Cerebral MRI and cervical + thoracic column MRI to check for Syringomyelia. Treatment depends on severity of symptoms and presence of syrinx. If symptoms are minimal ( e.g slight headache), follow up and anti pain (OTC) drugs are suggested, if there are significant neurologic symptoms, surgery is indicated ( decompression of posterior fossa). Hope this answers your question. If you have additional questions or follow up questions then please do not hesitate in writing to us. I will be happy to answer your questions.
