Glossary term:

Chiari-like malformation

This is a term used in veterinary medicine. Canine species have a cerebellum but do not have cerebellar tonsils. Certain toy breeds, in particular the cavalier King Charles spaniel, may nevertheless develop herniation of part of their cerebellum through the foramen magnum, causing the animal to develop symptoms and, in a significant proportion of cases, syringomyelia.
