This retrospective, multi‐institutional, descriptive study was performed to evaluate the CT features of exocrine pancreatic carcinomas. The CT examinations of 18 dogs and 12 cats with exocrine pancreatic carcinomas diagnosed by cytology or histopathology were reviewed. The CT features of exocrine pancreatic carcinomas included a well‐defined mass in 28/30 (93%) with contrast enhancement in 27/30 (90%), commonly heterogeneous 22/30 (73%); often with a nonenhancing fluid to soft tissue attenuating center 12/30 (40%). The right lobe of the pancreas was the most common location, 14/30 (47%), then the left lobe, 10/30 (33%), and the body, 6/30 (20%). Extrahepatic biliary duct dilation was present in six animals; 5/6 (83%) of the masses were located in the right pancreatic lobe. Additional findings included peripancreatic fat‐stranding 17/30 (57%), lymphadenopathy 16/30 (57%), peripancreatic soft tissue nodules 12/30 (40%), and free fluid 10/30 (33%). When comparing the imaging features of dogs and cats, there was a large overlap in imaging characteristics. There was a significant difference between the height of the masses, with dogs having larger masses ( P ‐value.0028). Lymphadenopathy was more likely in larger masses [increased height ( P ‐value.029)]. Cats were significantly older than dogs ( P ‐value.0355). Pancreatic carcinomas were commonly identified as masses with heterogeneous contrast enhancement and a nonenhancing fluid to soft tissue attenuating center with concurrent peripancreatic changes (fat‐stranding and/or soft tissue nodules) and lymphadenopathy.}, journal={VETERINARY RADIOLOGY & ULTRASOUND}, author={Dunn, Alexandra and Rao, Sangeeta and Husbands, Brian and Petrovitch, Nicholas and Loeber, Samantha and Schwarz, Tobias and Cline, Kelsey and Mai, Wilfried and Spain, Heather and Curran, Kaitlin and et al.}, year={2024}, month={Apr} }

Injuries included head trauma with an associated superficial lesion of the head and an overpronated left forelimb with a necrotic wound on the palmar surface. Osteomyelitis localised to the left forelimb was considered the primary differential based on radiographic findings and clinical signs. To treat osteomyelitis, regional antibiotic limb perfusions were conducted approximately once per week. After conducting seven total regional antibiotic limb perfusions, the patient's ambulation and mentation improved significantly and there was no progression of osteomyelitis on repeated radiographs. The patient was released to the wild after 5 months under human care. This case report demonstrates the potential use of regional antibiotic limb perfusion as an adjunctive therapy for osteomyelitis in chelonians.}, number={4}, journal={VetRecord CaseReports}, author={Cherukuri, A. and Scott -Cruz, S. and Lewbart, G. and Petrovich, N. and Ozawa, S.}, year={2022}, month={Dec}, pages={e487} }

Positioning of dogs with spontaneous pneumothorax during CT has not previously been evaluated. This retrospective, diagnostic accuracy study was performed to evaluate the sensitivity, positive predictive value (PPV), and interobserver variability for detection of pulmonary bullae with dogs positioned in multiple recumbencies. Dogs underwent CT in sternal and dorsal recumbency followed by thoracic exploration via median sternotomy. Three American College of Veterinary Radiology‐certified veterinary radiologists blinded to surgical findings reviewed dorsal and sternal images simultaneously. Severity of pneumothorax, degree of atelectasis, lesion location and size, and view in which lesions were most confidently identified were compared to surgical and histologic findings. Sensitivities and PPVs for bulla detection ranged from 57.7% to 69.2% and 62.1% to 78.9%, respectively. For two of the 3 radiologists, the location of bullae in the thorax was significantly associated with the recumbency in which the lesion was best identified. Degree of atelectasis was found to be associated with the ability to identify lesions (P ≤ .02). The interobserver variability for identification was good (κ = 0.670). The sensitivity of CT when performed in both sternal and dorsal recumbency is similar to that previously reported. Because the distribution of bullae is unknown prior to advanced imaging and bulla location affects which recumbency is most useful for identification, acquisition of CT images in both sternal and dorsal recumbency may improve detection of bullous lesions and aid surgical planning.}, number={6}, journal={VETERINARY RADIOLOGY & ULTRASOUND}, author={Dickson, Rachel and Scharf, Valery F. and Nelson, Nathan C. and Petrovitch, Nicholas and Keenihan, Erin K. and Mathews, Kyle G.}, year={2020}, month={Nov}, pages={641–648} }

Signalment, cause of trauma, fracture locations and characteristics, presence of neurological deficits, and 1‐week survival were recorded. Fractures were classified according to the extent of fragmentation and displacement.ResultsThe cranial vault was affected more frequently in dogs (P = .003), whereas the face and base of the cranium more often was affected in cats (P < .001). Cats presented with multiple fractures more frequently (P < .001). All animals with TSF in the cranial vault were more likely to develop neurological signs (P = .02), especially when depressed fractures were present (95% confidence interval [CI], 1.7‐8.2; P = .001). Animals with TSF located only in the facial region were less likely to have neurological signs (odds ratio with Mantel‐Haenszel's method [ORMH], 0.2; 95% CI, 0.1‐0.6; P = .004). Most affected animals (84.9%) survived the first week post‐trauma. Death was more likely with fractures of the cranial vault (P = .003), especially when fragmented (P = .007) and displaced (P = .004).Conclusions and Clinical ImportanceTraumatic skull fracture distribution and patterns are different between dogs and cats. Cranial vault fractures were associated with neurological deficits and worse survival. The presence of TSF alone should not be considered a negative prognostic factor because most affected animals survived the first week.}, number={5}, journal={JOURNAL OF VETERINARY INTERNAL MEDICINE}, author={Amengual-Batle, Pablo and Jose-Lopez, Roberto and Durand, Alexane and Czopowicz, Michal and Beltran, Elsa and Guevar, Julien and Lazzerini, Kali and De Decker, Steven and Munana, Karen and Early, Peter and et al.}, year={2020}, month={Sep}, pages={1975–1985} }
