Abstract
Chiari type 1 malformation is a developmental condition characterized by cerebellar herniation and syringohydromyelia in human beings. It has been reported as a common condition in the cavalier King Charles spaniel that is similar to human Chiari type 1 malformations. However, there are few documentations of diagnosed Chiari type 1 like malformation in other breed dogs. Abnormalities compatible with such a malformation were identified by magnetic resonance imaging in 24 dogs with neurologic signs in this study. The dogs were 15 females and 9 males. Their breed were variable, and 6 of the dogs were maltese, 5 were shih-tzu. The dogs had a variety of neurological signs and the severity of cerebellar herniation, syringohydromyelia, intracranial intra-arachnoid cyst or hydrocephalus.
