I'm looking for some help understanding type 4 Arnold-Chiari malformation. I've heard about it and I know it's a type of congenital brain malformation, but I'm not sure what it is and how it's different from other types of Arnold-Chiari malformation. Can anyone explain what type 4 Arnold-Chiari malformation is and why it's different from other types? Any information and advice would be greatly appreciated.
