An association between the occurrence of calcified discs, visible on radiographic examination (CDVR), and disc extrusions has been suggested in published literature over the past 10-20 years, mainly from Nordic countries. It has also been postulated that dogs without CDVR would not develop disc extrusions. Furthermore, inheritance of CDVR has been calculated and it has been postulated that, by selecting dogs for breeding with few, or no CDVR, the prevalence of disc extrusions in the Dachshund population may be reduced.

Concurrent occipital hypoplasia, occipital dysplasia, syringohydromyelia, and hydrocephalus in a Yorkshire terrier
Laura Cagle - Can Vet J. 2010 August; 51(8): 904–908.
Magnetic resonance imaging of a 7.5-year-old neutered male Yorkshire terrier with mild generalized ataxia and intermittent neck scratching led to a diagnosis of caudal occipital malformation and syringohydromyelia. Surgical exploration led to a diagnosis of occipital dysplasia with concurrent occipital hypoplasia. Following a dorsal laminectomy of the first cervical vertebra there was no progression or improvement a month later.

Diagnosis, treatment and prognosis of disc associated Wobbler syndrome in dogs
S. De Decker, S. Bhatti,I. Gielen, L. Van Ham
Disc associated wobbler syndrome (DAWS) is the most prevalent and most typical wobbler syndrome in dogs. It is typically seen in the middle-aged Dobermann Pinscher. Caudal cervical spinal cord compression is caused by protrusion of the annulus fi brosus of the intervertebral disc into the spinal canal, sometimes in combination with ligamentum fl avum hypertrophy and malformed vertebrae. Clinical signs vary from neck pain to tetraplegia. The diagnosis is generally made using myelography. There is a lot of controversy concerning the treatment of this disease. Many surgical techniques have been developed for it, but little is known about the results of conservative treatment. Objective data about the prognosis of this disease is scarce.

Horner’s Syndrome Associated with Glioblastoma Multiforme in a Dog
Aline de M. Viott , Roselene Ecco, Carla M.O. Silva, Gustavo O. Fulgêncio, Eliana G. Melo, Ingeborg M. Langohr
Abstract
A 7-year-old, intact female Bulldog was presented to the veterinarian with ocular signs characteristic of Horner’s Syndrome: bilateral conjunctival hyperemia, enophthalmos, miosis, and protrusion of the third eyelid of left eye. A month later, the dog returned for recheck with marked neurologic signs: lethargy, circling, constant vocalizing, depressed mentation, and hyperesthesia. A neoplasm in the brain was suspected. Treatment was implemented in an attempt to reduce clinical signs. After initial clinical remission, the clinical condition got worse and the owner elected euthanasia. Necropsy revealed a large intracranial neoplasm affecting an extensive portion of the cerebral parenchyma. The neoplasm was histologically diagnosed as glioblastoma multiforme. Determination of the extent of the affected cerebral regions based on neurologic exam was useful in establishing the presumptive clinical diagnosis of intracranial neoplasm. Horner’s syndrome preceded the neurologic signs in this dog. Although intracranial neoplasms such as glioblastomas multiformes are a rare cause of this syndrome, it is important to include them in the list of differential diagnoses in dogs in which this syndrome is seen in conjunction with neurologic signs.
