Progressive angiomatosis, resembling human skeletal-extraskeletal angiomatosis, arising in multiple digits in two dogs.

Two dogs presented with progressive, expansile and invasive lesions on a hind paw. Case 1, a 10-year-old female Shetland sheepdog had diffusive and aggressive-looking lesions on the middle digits of the left hind paw. Radiographic examination showed invasion into and destruction of the underlying bone.

Prevalence of incidental humeral intracondylar fissures in brachycephalic breed dogs in CT studies.

Humeral intracondylar fissures (HIF) have been predominantly reported in spaniel breeds and proposed to be possible risk factors for humeral condyle fractures (HCF). We hypothesized that the prevalence of incidental HIF in French Bulldogs may be greater than that of other brachycephalic breeds. A retrospective, observational, prevalence study was performed using CT examinations of French bulldogs and other brachycephalic breed dogs presenting for an unrelated condition.

Clinical findings and outcome following medical treatment in dogs with idiopathic renal haematuria: 41 cases (2001-2018).

Objectives: To characterise and document the progression of idiopathic renal haematuria in a large cohort of medically managed UK dogs.

Materials And Methods: Retrospective study of 41 client-owned dogs with confirmed (n=14), or suspected (n=27) idiopathic renal haematuria from 4 UK-based referral centres. Clinical findings and outcomes of dogs (2001 to 2018) were determined from the review of medical records and telephone follow-up.

Clinical relevance of radiographic linear branching mineral opacities in the canine liver.

Objectives: To assess the prevalence, clinical significance and breed distribution of linear branching mineralisation superimposed on the hepatic radiographic silhouette in dogs.

Materials And Methods: Retrospective review of radiographs or ultrasound images of dogs showing branching mineralisation in the liver.

Results: Over the 30-year review period, 17 cases were identified and the mineralisation had a predominantly ventral distribution.

Comparative anatomy and angiography of the cardiac coronary venous system in four species: human, ovine, porcine, and canine.

Introduction: The coronary arterial system has been the subject of greater investigation than its venous system due to the importance of human coronary artery disease. With the advent of new percutaneous treatments, the anatomy of the coronary venous system has increasing relevancy. We compared the organization of the coronary venous circulation in three species commonly used in research and compared these to normal humans using both macroscopic anatomic and angiographic studies.

Dogs with macroadenomas have lower body temperature and heart rate than dogs with microadenomas.

Pituitary macroadenomas compress the hypothalamus, which partly regulates heart rate and body temperature. The aim of this study was to investigate whether heart rate and/or body temperature could aid in clinically differentiating dogs with macroadenomas from dogs with microadenomas (i.e.

COMPARISON BETWEEN COMPUTED TOMOGRAPHIC CHARACTERISTICS OF THE MIDDLE EAR IN NONBRACHYCEPHALIC AND BRACHYCEPHALIC DOGS WITH OBSTRUCTIVE AIRWAY SYNDROME.

Prevalence of subclinical middle ear lesions in dogs that undergo computed tomography (CT) and magnetic resonance imaging of the head has been reported up to 41%. A predisposition in brachycephalics has been suggested, however evidence-based studies are lacking. Aims of this retrospective cross-sectional study were to compare CT characteristics of the middle ear in groups of nonbrachycephalic and brachycephalic dogs that underwent CT of the head for conditions unrelated to ear disease, and test associations between thickness of the soft palate and presence of subclinical middle ear lesions.

Hypertrophic osteopathy in a cat with a concurrent injection-site sarcoma.

An 11-year old neutered female domestic shorthair cat presented for investigation of a large, partially ulcerated skin mass in the area of the left scapula. The cat had been vaccinated 6 weeks previously in the same area. Haematology showed a marked neutrophilia and monocytosis.

Capturing the cloud of diversity reveals complexity and heterogeneity of MRSA carriage, infection and transmission.

Genome sequencing is revolutionizing clinical microbiology and our understanding of infectious diseases. Previous studies have largely relied on the sequencing of a single isolate from each individual. However, it is not clear what degree of bacterial diversity exists within, and is transmitted between individuals.

CT dimensions, volumes and densities of normal canine eyes.

Although ultrasound and MRI are the imaging modalities of choice for the investigation of ocular diseases, the eyes are included in routine CT examinations of the head and should be examined as part of the complete evaluation. This report describes the dimensions, volumes and densities of the normal canine globe in CT. Forty-four eyes were studied.

Diagnostic value of MRI in dogs with inflammatory nasal disease.

Objectives: To determine the value of low-field magnetic resonance imaging in differentiating sino-nasal aspergillosis from lymphoplasmacytic rhinitis in dogs.

Methods: A retrospective study of 41 dogs (25 with lymphoplasmacytic rhinitis and 16 with sino-nasal aspergillosis) that underwent magnetic resonance imaging scan of the nasal cavity was conducted. On magnetic resonance imaging, turbinate destruction was classified as mild, moderate or severe.

Diagnostic accuracy of three biopsy techniques in 117 dogs with intra-nasal neoplasia.

Objectives: To determine if nasal biopsies taken at rhinoscopy are more accurate for diagnosing neoplasia than biopsies taken blindly or using advanced imaging for guidance.

Methods: A retrospective study of 117 dogs with nasal mass lesions that were divided into three groups according to the method of nasal biopsy collection; advanced imaging-guided, rhinoscopy-guided and blind biopsy. Signalment, imaging and rhinoscopic findings, and histopathological diagnosis were compared between groups.

Exclusion of a brain lesion: is intravenous contrast administration required after normal precontrast magnetic resonance imaging?

Background: No evidence-based guidelines are available for the administration of gadolinium-based contrast media to veterinary patients.

Objective: To investigate whether administration of intravenous (IV) contrast media alters the likelihood of identifying a brain lesion in dogs and cats.

Animals: Four hundred and eighty-seven client-owned animals referred for investigation of intracranial disease.

Loeffler's endocarditis and bicavity eosinophilic effusions in a dog with visceral mast cell tumour and hypereosinophilia.

A 9-year-old crossbred dog was presented with a 2-week history of diarrhoea and tachypnoea. Marked circulating eosinophilia was identified. Pleural and abdominal effusions were detected by radiography and ultrasonography and cytological examination of these fluids revealed a predominance of eosinophils.

Clinical and low-field MRI characteristics of injection site sarcoma in 19 cats.

Magnetic resonance imaging (MRI) has been recommended for staging and surgical planning in cats with injection site sarcomas (ISS). The purpose of this retrospective study was to describe low-field MRI characteristics of confirmed injection site sarcomas in a group of cats. Low-field MR images, thoracic radiographs, histopathology findings, and medical records of cats that fulfilled histological criteria of injection site sarcoma were retrieved and reviewed retrospectively.

Magnetic resonance imaging features of canine incomplete humeral condyle ossification.

Incomplete ossification of the humeral condyle (IOHC) is characterized by an intracondylar fissure located where the intercondylar physis is present in growing dogs. Its radiologic and computed tomographic features have been described but the magnetic resonance (MR) features have not been characterized. Our purpose was to further describe the range of MRappearances of IOHC, to assess the diagnostic capability of MRrelative to radiology, and to determine whether MRis able to identify the disease before a fissure forms.

Unilateral hydronephrosis and hydroureter secondary to ureteric atresia, and uterus unicornis in a young terrier.

A nine-month-old entire female terrier cross was presented with intermittent anorexia, vomiting and recent onset of abdominal pain and distension. A diagnosis of unilateral hydronephrosis was made following ultrasound examination and intravenous urography, but no cause was identified. Subsequent ureteronephrectomy and histology of the affected kidney showed ureteric atresia as the cause of obstruction.

Hypovitaminosis D in dogs with inflammatory bowel disease and hypoalbuminaemia.

Objectives: To compare serum vitamin D metabolites and plasma parathyroid hormone concentrations in dogs with inflammatory bowel disease and normal albumin concentration, dogs with inflammatory bowel disease and hypoalbuminaemia, healthy dogs and hospitalised ill dogs with non-gastrointestinal illness.

Methods: Serum 25 hydroxyvitamin D and 1,25 dihydroxyvitamin D concentrations were measured in 36 healthy dogs, 49 hospitalised ill dogs with non-gastrointestinal illnesses, 21 dogs with inflammatory bowel disease and normoalbuminaemia and 12 dogs with inflammatory bowel disease and hypoalbuminaemia. Plasma parathyroid hormone and ionised calcium concentrations were measured in a subset of these dogs.
