An Airedale Terrier was presented for evaluation of depression and reluctance to be touched on the head. Magnetic resonance (MR) imaging of the head was performed. The images revealed bone lesions affecting the calvarium at the level of the coronal suture and left mandibular ramus, with focal cortical destruction, expansion, and reactive new bone formation. Skull lesions were hypointense on T1‐weighted sequences, hyperintense on T2‐weighted sequences, and showed an intense and homogeneous enhancement after gadolinium administration. Reactive new bone formation and periosteal proliferation were confirmed histopathologically. The clinical signs, imaging findings, and histopathological examination were consistent with craniomandibular osteopathy. 相似文献

Canine dysautonomia was diagnosed definitively in five dogs by histopathology. All dogs were seen between June 2004 and July 2006 and originated from south-east England; four dogs originated from an urban area and one from a rural area. Of the urban dogs, one had recently visited Scotland and one had visited a kennel in a rural area nearby. Acute-onset but progressive vomiting, diarrhoea, depression and inappetence were the most common presenting clinical signs. Reduced or absent anal tone, dysuria, absence of pupillary light reflexes with intact vision, mydriasis, decreased corneal sensitivity and nictitating membrane protrusion were among the most frequent neurological findings. Abnormalities in pharmacological autonomic and physiological function testing (including orthostatic hypotension in two dogs) and diagnostic imaging studies were detected in some of the animals. All dogs failed to respond adequately to treatment, and given the poor prognosis, they were eventually euthanased. Histopathology identified marked chromatolysis of ganglion cell bodies. This case series emphasises that dysautonomia should be considered when a dog is presented in the UK with acute- or subacute-onset gastrointestinal signs and compatible physical and neurological abnormalities. 相似文献

Three cases of discospondylitis in the dog, caused respectively by Pseudomonas aeruginosa, Enterococcus faecalis and Staphylococcus epidermidis, are reported. These bacteria have not previously been documented as being the cause of the condition in this species. The neurological involvement was severe in all three cases. Two dogs were paraplegic and one was tetraplegic, and one of the paraplegic dogs had no deep pain on the extremities of both pelvic limbs. All dogs were treated surgically with a satisfactory neurological recovery. 相似文献

The aim of this study was to identify magnetic resonance (MR) signs that aid differentiation of neoplastic vs. non-neoplastic brain diseases in dogs and cats. MR images of 36 dogs and 13 cats with histologic diagnosis of intracranial disease were reviewed retrospectively. Diagnoses included 30 primary and three metastatic brain tumors, 11 infectious/inflammatory lesions, three vascular, one degenerative disease, and one developmental malformation. Upon univariate analysis of 21 MR signs, there were seven that had a significant association with neoplasia: single lesion (P = 0.004), shape (P = 0.015), mass effect (P = 0.002), dural contact (P = 0.04), dural tail (P = 0.005), lesions affecting adjacent bone (P = 0.008), and contrast enhancement (P = 0.025). Increasing age was also found to be associated with neoplasia (P = 0.0001). MR signs of non-neoplastic brain diseases in dogs and cats were more variable than those of brain neoplasia. 相似文献

Background
Corpus callosal abnormalities (CCA) in dogs have been only sporadically reported and are poorly characterized.Hypothesis/Objectives
To describe the clinical presentation and magnetic resonance imaging (MRI) characteristics of dogs with CCA.Animals
Fifteen client‐owned dogs.Methods
Retrospective study. Records of the contributing institutions were reviewed to identify dogs diagnosed with malformations affecting the corpus callosum (CC); cases in which the CCA was thought to be secondary were excluded.Results
The most represented breeds were Staffordshire Bull Terriers (5/15) and Miniature Schnauzers (3/15; n = 3, 20%) and the mean age at time of presentation of 19 months (range 3–81 months). The clinical signs most commonly reported were adipsia/hypodipsia with associated hypernatremia (12/15), tremors (6/15), and seizures (6/15). Review of the MR images revealed that 10 dogs had absence of the rostral CC and hypoplasia of the caudal portion, 4 dogs had a diffusely hypoplastic and dysplastic CC, and 1 dog had a diffusely hypoplastic CC. In 14 cases, there was abnormal cortical development with fusion of the ventral frontal lobes and part of the diencephalon, indicating lobar holoprosencephaly.Conclusions and Clinical Importance
Previous literature has mainly associated CCA with adipsia and only 12 of 15 dogs in the current series demonstrated this abnormality. There are different degrees of the malformation but in 10 dogs the rostral portion of the CC is most severely affected. Fourteen dogs have simultaneous fusion of the midline structures rostral to the CC; this region has several structures involved in thirst regulation and might explain this derangement. 相似文献6.

Objective-To investigate the effect of intraoperative extradural morphine administration on postoperative analgesia in dogs undergoing thoracolumbar spinal surgery to treat disk extrusion. Design-Prospective clinical trial. Animals-26 client-owned dogs undergoing thoracolumbar spinal surgery. Procedures-Animals were randomly allocated to receive morphine (0.1 mg/kg [0.045 mg/lb], extradurally) or no treatment (control group). Following preanesthetic medication with methadone (0.25 mg/kg [0.11 mg/lb], IM), anesthesia was induced with propofol and maintained with isoflurane or sevoflurane in oxygen. Lidocaine and fentanyl were administered during surgery in both groups at fixed rates. In the morphine administration group, morphine was splashed over the dura mater immediately prior to wound closure. Postoperative analgesia was assessed for 48 hours by assessors unaware of group allocation, and methadone was administered as rescue analgesic. Demographic characteristics, urinary output, days of hospitalization, and perioperative use of analgesics were compared via a Mann-Whitney U test. Results-Demographic data were similar between groups. In the morphine administration group, 2 of 13 dogs required postoperative methadone, and in the control group, methadone was administered to 11 of 13 dogs. The total number of doses of methadone administered in the 48 hours after surgery was 28 in the control group and 3 in the morphine administration group. No adverse effects were recorded in any group. Conclusions and Clinical Relevance-Intraoperative extradural morphine administration was effective in reducing postoperative analgesic requirement. Dogs undergoing thoracolumbar spinal surgery benefited from topical administration of preservative-free morphine administered directly on the dura mater as part of analgesic management. 相似文献

Idiopathic hypertrophic pachymeningitis has been described in humans as a rare, chronic progressive non-specific inflammatory and fibrotic disease of the dura mater. This is a case series of six canine cases of presumptive or confirmed intracranial idiopathic hypertrophic pachymeningitis. These dogs were included in this retrospective study, based on magnetic resonance imaging findings. All presented with pachymeningeal thickening and enhancement without involvement of the leptomeninges on magnetic resonance imaging and no underlying cause identified on cerebrospinal fluid analysis, complete blood count, serum biochemistry and infectious disease titres. Histopathological examination was available in one case. Response to immunomodulatory treatment (corticosteroids and cytosine arabinoside) was achieved in five cases. Idiopathic hypertrophic pachymeningitis should be considered as a possible differential diagnosis for dogs with pachymeningeal thickening on magnetic resonance imaging and no identified underlying cause. The prognosis appears to be fair to poor. 相似文献
