Acquired scoliosis associated with hydromyelia and syringomyelia in two dogs

Abstract

Progressive scoliosis resulting from hydromyelia and syringomyelia was found in 2 dogs. In one dog, hydromyelia was associated with pachymeningeal fibrosis, with adhesions in the cervical portion of the spinal cord. In the other case, a cause was not established. Neither dog had congenital CNS malformations. The clinicopathologic findings in the 2 dogs are described, and the etiology and pathogenesis of hydromyelia and syringomyelia are discussed.
