Arnold-Chiari Malformation Support Group
Arnold-Chiari malformation, sometimes referred to as 'Chiari malformation' or ACM, is a congenital anomaly of the brain. Arnold-Chiari Malformation II occurs in almost all children born with both spina bifida and hydrocephalus, but ACM I is typically seen in children and adults without spina bifida.
However, that can go well...or not. For your sake, I do hope it goes well. If the NL doesn't seem to take it seriously and send you on to a NSG, in spite of your debilitating symptoms, then see what you can do about getting to an expert.
Let us know what the NL says and take good care of yourself!
