My daughter recently had a CT scan and was just diagnosed with Chiari Malformation 1 with 1.3 cm. Today she had an MRI and is scheduled to see a Nerosurgeon after the first of the year. I have read a lot of informaiton on line about Chiari and understand what it is, but I am wondering if 1.3 cm is considered good or bad? She has been suffering from headaches and dizziness for a couple of months now and it just keeps getting worse. Any in sight you can give me would be appreciated, her appointment is still a month away.
