Chiari malformation : Arnold chiari malformation type 1 is defined by cerebellar tonsils that extend below the foramen magnum. The symptoms range from none to headaches, numbness, pain and weakness. The condition can become life threatening when cerebrospinal fluid is blocked. It is important to see a neurosurgeon with experience treating this disorder to discuss the therapeutic options.
