Odontogenic neoplasms are locally invasive oral tumors in dogs. The purpose of this retrospective study was to describe CT characteristics for varying histopathologic types canine odontogenic neoplasms. A board‐certified veterinary radiologist who unaware histologic findings reviewed and scored imaging studies. total 29 dogs were included the study. Twenty‐three these had concurrent dental radiographs. most common all tumor a direct association with or region multiple teeth 96.4% (27/28),...
Summary Objective: To determine outcome, report complications, and risk factors for complications associated with the surgical treatment of fractures lateral aspect humeral condyle (FLHC) in dogs. Study design: Fifty dogs FLHC that had been repaired surgically were included this retrospective case series. Methods: The medical records radiographs from 50 1990–2006 analyzed. Results: complication rate was 30%. For every 30-minute increase time odds a increased by 2.00 (95% CI: 1.06, 3.77). 10°...
Ossifying fibroma (OF) and fibrous dysplasia (FD) are benign, intraosseous, proliferative fibro-osseous lesions (PFOLs) characterized by replacement of normal bone a matrix with various degrees mineralization ossification. Osteomas benign tumors composed mature, well-differentiated bone. Clinical, imaging, histologic features 15 initially diagnosed PFOLs osteomas the canine oral cavity were evaluated. Final diagnoses after reevaluation as follows: OF (3 cases), FD (4 low-grade osteosarcoma...
Pleural space masses and nodules are rarely described on computed tomography ( CT ) in veterinary medicine have only been patients with neoplasia. Our purpose was to describe the findings diagnoses seven pleural nodules. Two had broad‐based, plaque‐like masses, both of which were due neoplasia (primary carcinoma, metastatic thymoma). well‐defined nodular thickening, one mesothelial hypertrophy, another hemangiosarcoma. Three ill‐defined pulmonary while other two bacterial infection...
The 2008 World Health Organization Cancer Report describes global cancer incidence soaring with many patients living in countries that lack resources for control. Alternative treatment strategies can reduce the disease burden at manageable costs must be developed. Polysaccharopeptide (PSP) is bioactive agent from mushroom Coriolus versicolor. Studies indicate PSP has vitro antitumor activities and inhibits growth of induced tumors animal models. Clear evidence clinically relevant benefits...
To describe the diagnostic utility and clinical safety of ultrasonographically guided percutaneous pyelocentesis antegrade pyelography in cats dogs.Retrospective case series.39 10 dogs with 55 affected kidneys.Medical records were reviewed to identify that underwent between June 1, 2007, December 31, 2015. Data collected included procedure descriptions; results imaging, urine cytologic evaluation, bacterial culture; evidence complications. Animals assigned group (underwent only...
In a solar particle event (SPE), an unshielded astronaut would receive proton radiation with energy profile that produces highly inhomogeneous dose distribution (skin receiving greater than internal organs). The novel concept of using megavoltage electron-beam to more accurately reproduce both the total and SPE protons make meaningful RBE comparisons between conventional has been described previously. Here, Yucatan minipigs were used determine effects superficial, SPE-like electrons. these...
Background Survival times and tumor responses associated with malignant neoplasia of the lower urinary tract are poor despite vast array current treatments. Therefore, evaluation alternative treatments, such as intraarterial administration chemotherapy ( IAC ) should be considered. Objective To describe a technique for superselective catheterization to evaluate initial response by ultrasonography after both intravenous IVC ). Animals Client‐owned dogs treated either (n = 15) or 11). Methods...
Objective To determine the sensitivity, specificity, and predictive value of ultrasonography for localizing hepatic masses in dogs to identify patient factors associated with diagnostic accuracy. Study Design Retrospective cross‐sectional study. Animals Client‐owned (n = 137). Methods Medical records diagnosed a solitary mass on abdominal ultrasound confirmed by laparotomy or laparoscopy were reviewed. Location predicted was compared location identified at surgery. Ultrasound exams performed...
Abstract Background Diagnosis of infiltrative small intestinal (SI) disease in cats is challenging, and debate continues regarding optimal biopsy techniques. Ultrasonography may facilitate selection type location. Hypothesis/Objectives Assess ability ultrasonography to predict histologic lesions by SI segment tissue layer.

Eighty-nine 32 cytology and/or histopathology were categorized into malignant disease (15 11 cats), pyothorax (34 7...
Abstract Urothelial carcinoma (UC) occurs uncommonly in cats and no association has previously been observed with long‐term indwelling urinary implants. An 18‐year‐old male castrated domestic shorthair cat initially was presented for hematuria, leading to the diagnosis of a right‐sided ureterolithiasis severe pyelectasia on ultrasound examination, prompting subcutaneous ureteral bypass (SUB) device placement. The subsequently had intermittent hematuria dysuria, without ultrasonographic...
