“…On the basis of the present results, it is uncertain whether the observed malformation contributes to the observed neurological signs or has no clinical effect. For example, the persistent scratching of the shoulder or neck by some cavalier King Charles spaniels is an unusual sign which may be related to syringohydromyelia (Churcher andChild 2000, Rusbridge andothers 2000), but, as was observed in this study, it is not a consistent sign in dogs with syringohydromyelia. Furthermore, one of the dogs with the malformation was clinically normal, and some of the clinically affected dogs recovered without treatment.…”

Neurological signs and results of magnetic resonance imaging in 40 cavalier King Charles spaniels with Chiari type 1‐like malformations

In human beings a Chiari type 1 malformation is a developmental condition characterised by cerebellar herniation and syringohydromyelia. Abnormalities compatible with such a malformation were identified by magnetic resonance imaging in 39 cavalier King Charles spaniels with neurological signs and in one neurologically normal cavalier King Charles spaniel that was examined postmortem. The dogs with these abnormalities had a wide variety of neurological signs, but there was no apparent correlation between the neurological signs and the severity of cerebellar herniation, syringohydromyelia or hydrocephalus.

“…A bnormalities in caudal fossa morphology are increasingly recognized as a cause of morbidity in many small breed dogs, especially in the Cavalier King Charles Spaniel. Specifically, Chiari‐like malformations and syringohydromyelia have become a serious health concern for this breed 1–9 . Dogs affected with Chiari‐like malformation and/or syringohydromyelia have clinical signs including occasional to constant scratching of the head and neck region, severe neck pain, scoliosis and gait changes 7,9–13 …”

Chiari malformations and syringohydromyelia are an important disease complex in Cavalier King Charles Spaniels. Although abnormalities in caudal fossa morphology are considered major contributors to the development of this disease, limited information exists on the range of morphologies in Cavalier King Charles Spaniels and on the relationship of these to clinically evident disease. Sixty-four Cavalier King Charles Spaniels were studied. Each underwent a neurologic examination and magnetic resonance imaging of the cervical spine and brain. T2-weighted sagittal images were used to determine both the morphologic characteristics and volume of the caudal fossa in each dog. This volume was also analyzed as a percentage of total cranial cavity volume. Each attribute was correlated with neurological grade and presence of syringohydromyelia. Fifteen dogs had neurologic signs, and 59 had morphologic abnormalities of the craniocervical junction. While 27 dogs had syringohydromyelia, 13 of these were clinically normal. Cerebellar herniation and occipital dysplasia were common findings but were not associated with syringohydromyelia. Dorsal compressive lesions were noted at the first and second cervical vertebral junction. Factors associated with the presence of neurologic signs included syringohydromyelia and the ratio of caudal fossa/total cranial cavity volume; dogs with signs had significantly larger syringohydromyelia than asymptomatic dogs. Caudal fossa size was not associated with syringohydromyelia. A positive association was identified between foramen magnum size and length of cerebellar herniation. The prevalence of craniocervical junction abnormalities is high in Cavalier King Charles Spaniels. While several factors are associated with neurologic signs, occipital hypoplasia appears to be the most important factor.

“…Non-steroidal anti-inflammatory drugs, corticosteroids, gabapentin, and oral opioids can be used for the treatment of SM [10]. The most common procedure performed is foramen magnum decompression, where the hypoplastic occipital bone and sometimes the cranial dorsal laminae of the atlas are removed (with or without a durotomy) to decompress the foramen magnum [1,3]. …”

Syringomyelia in three small breed dogs secondary to Chiari-like malformation: clinical and diagnostic findings

et al. 2009

View full text Add to dashboard Cite

Three small breed dogs were referred for the evaluation of neurologic deficits. Upon physical and neurologic examination, all dogs displayed hyperesthesia, pain, and neck stiffness. Magnetic resonance imaging was performed on the brain and spinal cord, and all three dogs presented Chiari-like malformations and syringomyelia. These dogs were treated with prednisolone and furosemide, and showed rapid improvement of clinical signs. Chiari malformations and syringomyelia were not improved because of congenital disorders. This case report demonstrates the clinical and diagnostic features of Chiari-like malformations and syringomyelia in three small breed dogs.
