In brief: Big difference
Arnold chiari is a chiari ii malformation which is usually associated with spina bifida and involves herniation of the cerebellar vermis.
On the other hand, what typically is diagnosed in young adults is a chiari i malformation which involves herniation of the cerebellar tonsil and is not associated with a neural tube defect.

In brief: Clinical findings
Chiari described different forms of malformation of the cerebellum. His type 2 was found associated with spina bifida and other defects in formation of the brain, brainstem, and spinal cord.
This was elaborated by arnold. Therefore, chiari 2 has now been called the arnold chiari malformation.
