Chiari-like malformation (CM) and syringomyelia are components of a structural central nervous system disease syndrome that primarily affects Cavalier King Charles spaniels (CKCS) and other small-breed dogs (BOX 1).CM is referred to in the veterinary literature by various names, including caudal occipital malformation syndrome, occipital dysplasia, Chiari malformation, and hindbrain herniation. TV.com. After perfusion, the brains and spinal cords were quickly dissected and taken out. The most common symptom that develops is intermittent neck pain, although back pain is also possible. Syringomyelia is a painful condition affecting the spinal cord of dogs, found most commonly in Cavalier King Charles Spaniels. Syringomyelia is a condition characterized by a fluid-filled cavity or cyst known as a syrinx that forms within the spinal cord. Early estimates of the heritability of syringomyelia suggest values of around 0.7-0.8, that is, that 70-80% of the variation between individuals is genetic in origin and about 20-30% is environmental (Working Group 2008), and that approximately three-quarters of dogs bred from affected animals are likely to inherit the condition (Blott 2008). Syringomyelia is the term that describes fluid-filled cavities that develop within the spinal cord causing abnormal sensation in affected dogs. Dogs may cry out for no obvious reason as well as when touched. Surgery is also very expensive. Some dogs with syringomyelia may not have any symptoms; however, when present the most common symptom is neurological pain, particularly in the neck. Symptomatic syringomyelia (SM) and concomitant Chiari-like malformation (CM) is a neurological syndrome that occurs in up to 15% of Cavalier King Charles Spaniels (CKCS) (Thøfner et al. Introduction.

It has also been diagnosed in Brussels Griffons, Chihuahuas, Yorkies, Maltese, Miniature Dachshunds, Pomeranians, French Bulldogs, Boston Terriers, Pugs, and other breeds. Syringomyelia is a chronic condition of the central nervous system in which (typically) a Chiari-like malformation of the brain tissue causes a blockage of the foramen magnum (the "valve" between the brain cavity and spinal column) and increased pressure of the cerebrospinal fluid along the spinal cord. CLM describes a mismatch between the size of the brain, which is too big, and the space within the skull, which is too small.
