Abstract
West Highland white terriers (WHWTs) affected with canine idiopathic pulmonary fibrosis (CIPF) are at risk of developing precapillary pulmonary hypertension (PH). In humans, thoracic computed tomography angiography (CTA) is commonly used to diagnose and monitor patients with lower airway diseases. In such patients, CTA helps to identify comorbidities, such as PH, that could negatively impact prognosis. Diameter of the pulmonary trunk (PT), pulmonary trunk-to-aorta ratio (PT/Ao), and right ventricle-to-left ventricle ratio (RV/LV) are CTA parameters commonly used to assess the presence of PH. Pulmonary vein-to-right pulmonary artery ratio (PV/PA) is a new echocardiographic parameter that can be used in dogs to diagnose PH. The primary aim of this study was to evaluate the use of various CTA parameters to diagnose PH. An additional aim was to evaluate the correlation of RV/LV measurements between different CTA planes. CTA and echocardiography were prospectively performed on a total of 47 WHWTs; 22 affected with CIPF and 25 presumed healthy control dogs. Dogs were considered to have PH if pulmonary vein-to-right pulmonary artery ratio (PV/PA) measured on 2D-mode echocardiography was less than to 0.7. WHWTs affected with CIPF had higher PT/Ao compared with control patients. In WHWTs affected with CIPF, PT size was larger in dogs with PH (15.4 mm) compared with dogs without PH (13 mm, p = 0.003). A cutoff value of 13.8 mm predicted PH in WHWTs affected with CIPF with a sensitivity of 90% and a specificity of 87% (AUC = 0.93). High correlations were observed between the different CTA planes of RV/LV. Results suggest that diameter of the PT measured by CTA can be used to diagnose PH in WHWTs with CIPF.

Abstract
Canine idiopathic pulmonary fibrosis is a progressive interstitial lung disease mainly affecting West Highland white terriers. Thoracic high-resolution computed tomographic (T-HRCT) findings for Canine idiopathic pulmonary fibrosis acquired under general anesthesia have been described previously. However, the use of general anesthesia may be contraindicated for some affected dogs. Sedation may allow improved speed and safety, but it is unknown whether sedation would yield similar results in identification and grading of Canine idiopathic pulmonary fibrosis lesions. The aim of this prospective, observational, method-comparison, case-control study was to compare findings from T-HRCT images acquired under sedation versus general anesthesia for West Highland white terriers affected with Canine idiopathic pulmonary fibrosis (n = 11) and age-matched controls (n = 9), using the glossary of terms of the Fleischner Society and a scoring system. Ground-glass opacity was identified in all affected West Highland white terriers for both sedation and general anesthesia acquisitions, although the Ground-glass opacity extent varied significantly between the two acquisitions (P < 0.001). Ground-glass opacity was the sole lesion observed in control dogs (n = 6), but was less extensive compared with affected West Highland white terriers. Identification and grading of a mosaic attenuation pattern differed significantly between acquisitions (P < 0.001). Identification of lesions such as consolidations, nodules, parenchymal and subpleural bands, bronchial wall thickening, and bronchiectasis did not differ between acquisitions. The present study demonstrated that T-HRCT obtained under sedation may provide different information than T-HRCT obtained under general anesthesia for identification and grading of some Canine idiopathic pulmonary fibrosis lesions, but not all of them. These differences should be taken into consideration when general anesthesia is contraindicated and sedation is necessary for evaluating West Highland white terriers with Canine idiopathic pulmonary fibrosis.

Abstract
Diffusion-weighted MRI (DW-MRI) and (18)F-fluorodeoxyglucose positron emission tomography (FDG-PET) findings are described in a patient with a thoracic aortic aneurysm. Both examinations have the ability to noninvasively assess biological processes associated with aneurysm instability and therefore to potentially impact clinical decision-making regardless of the vessel size. Despite similarities between images on both techniques, FDG-PET evaluates glycolysis, while DW-MRI evaluates cell density, edema, and perfusion. Longitudinal studies including larger patient numbers are needed to investigate the temporal continuum and clinical significance of these findings.

Abstract
Reaching etiologic diagnoses for retroperitoneal fibrosis may be challenging. We report the case of a 75-year old male with history of ruptured abdominal aortic aneurysm and subsequent retroperitoneal fibrosis who developed four years later a soft tissue infiltration surrounding the ascending thoracic aorta. Thanks to his medical records and multimodality imaging assessment, the patient escaped an open-chest biopsy through histolgical reassessment of the abdominal periaortic samples that allowed the definitive diagnosis of Erdheim-Chester disease, a rare non-Langerhans histiocytosis.

Abstract
The use of a novel ultrasonic osteotome enabled the authors to modify well-established orthognathic osteotomies to more favourably address the anatomy. For this purpose, they utilized a powerful ultrasonic device with tissue-selective cutting characteristics that was originally developed for spinal osteotomies and nerve decompression (BoneScalpel™ by Misonix Inc., Farmingdale, NY, USA). Its straight ultrasonic blade was adapted for dual action, and a soft protective element was added. The product modifications and the related changes regarding maxillary and mandibular osteotomies are explained in detail. A series of 83 patients underwent orthognathic surgery with the BoneScalpel ultrasonic osteotome. All osteotomies within this study group were performed purely ultrasonically and without the auxiliary use of reciprocating saws or rotary burrs. The complications, alveolar nerve impairment and bad splits were assessed. To assess the quality of the lingual osteotomies and pterygomaxillary separation, three-dimensional scanning was performed on 30 patients. In conclusion, the BoneScalpel™ ultrasonic osteotome enabled improved control over orthognathic osteotomies and resulted in significant reductions in the occurrence of nerve impairment and bad splits.

Abstract
Portal venous gas is a worrying radiological sign that was described for the first time in 1955 among newborn children suffering from necrotizing enterocolitis. It was often related to mesenteric ischemia which mortality remains very high. Now, as radiological explorations increase, portal venous gas is more and more described in less pejorative contexts, such as hydrogen peroxide intoxication. It is what happened to our patient who underwent a hydrogen peroxide colic enema followed by a major and transient portal venous gas onset. This solved quickly and spontaneously.

Abstract
Recently a new computed tomography semiology of the pulmonary adenocarcinoma was highlighted. Studies on ground-glass nodule and on mixed nodule showed the relation between these radiological images and the different anatomopathological forms of lung adenocarcinoma. Ground-glass opacity can correspond to precancerous lesions and morphological characteristics of nodules are correlated with the prognosis. The presence of spiculation, pleural retraction and air bronchogram is significantly more important in neoplasic lesions. The presence or the apparition of a solid component inside the nodule or the presence of indentation is highly suggestive of adenocarcinoma. A lesion smaller than 20 mm and persistant after 1 month must be, either followed up, or removed by a limited surgical resection. Lesions larger than 20 mm or associated with a solid component must be treated by conventional surgery.
