Although magnetic resonance imaging has been used to examine the brain of domestic ruminants, detailed information relating the precise anatomical features in these species is lacking. In this study the brain structures of calves (Bos taurus domesticus), sheep (Ovis aries), goats (Capra hircus) and a mesaticephalic dog (Canis lupis familiaris) were examined(More)
BACKGROUND Understanding the pathogenesis of the chiari-like malformation in the Cavalier King Charles Spaniel (CKCS) is incomplete, and current hypotheses do not fully explain the development of syringomyelia (SM) in the spinal cords of affected dogs. This study investigates an unconventional pathogenetic theory for the development of cerebrospinal fluid(More)
BACKGROUND Neuropathic pain can be a clinical sign in Cavalier King Charles Spaniels (CKCS) with syringomyelia. The pathophysiology of this pain is not fully understood. HYPOTHESIS Neuropathic pain in CKCS is a result of a neuroinflammatory process. ANIMALS Twenty-six client-owned dogs: 15 dogs with clinical signs of cervical hyperesthesia (group 1),(More)
Premature closure of cranial base synchondroses has been proposed as the mechanism for brachycephaly in dogs and caudal occipital malformation syndrome (COMS) in Cavalier King Charles Spaniels. The purpose of this retrospective study was to compare times of closure for cranial base synchondroses in mesaticephalic, brachycephalic, and Cavalier King Charles(More)
A 4-year-old, 30.6-kg castrated male mixed-breed dog was referred for evaluation of acute diarrhea, inappetence, weight loss, and lethargy. The dog had otherwise been healthy since being adopted from a Greek animal shelter 18 months before presentation. The only other household pet was its clinically healthy littermate. On examination, the dog was(More)
A 12-year-old domestic shorthair cat was presented with neurologic signs localized to the forebrain. Magnetic resonance imaging (MRI) of the brain revealed a space occupying lesion within the third and the lateral ventricles. The lesion had areas of disparate signal characteristics and exerted a mass effect on the surrounding parenchyma and ventricular(More)
BACKGROUND Magnetic resonance imaging (MRI) findings of canine brains with enlarged ventricles in asymptomatic dogs were compared to those in dogs with clinically relevant internal hydrocephalus, in order to determine the imaging findings indicative of a relevant increase in intraventricular pressure. Discrimination between clinically relevant hydrocephalus(More)
German shepherd dogs are overrepresented in the group of dogs with cauda equina compression syndrome due to degenerative lumbosacral stenosis. A congenital predisposition for early degeneration of the lumbosacral intervertebral disc has been suspected. Our aims were to assess the morphologic appearance of the lumbosacral intervertebral disc and the(More)
OBJECTIVE The diagnostic value of CT and MRI regarding the diagnosis of coronoid pathology in the dog. MATERIAL AND METHODS Computed tomography (CT) and magnetic resonance imaging (MRI) of the elbow joint were performed in dogs with clinical and radiological signs of coronoid pathology. Afterwards, all dogs underwent arthroscopic surgery. For the computed(More)
The aim of this study was to identify skeletal variations in the lumbosacral junction (LSJ) of the German shepherd dog (GSD) compared with other large breeds. The radiographic traits of the LSJ were investigated in a group of 733 GSDs and a control group of 334 dogs of other breeds that were matched in terms of size. Nine morphological and 17 morphometric(More)
