Notice the enlarged left atrium summates as an ovoid soft tissue opacity over the mid-caudal aspect of the cardiac silhouette. Red blood cells are also visible in the background. This is another example why it is important to use more than one projection to determine if there is cardiomegaly and chamber enlargement. In these cases, the left auricle is seen as a soft tissue convexity on the cardiac silhouette at the 2-3 o’clock position on the ventrodorsal or dorsoventral projections.

Radiographically, it presents as bilateral, dorsal or diffuse, interstitial or alveolar infiltrate. Antibiotics should be continued for 1-2 weeks after radiographs are normal. Breitschwerdt, L. Guardabassi, D.H. Lloyd, M.G. Note the consolidation of the right middle lung lobe. These signs include a heart murmur, tachycardia, decreased perfusion (i.e. In this article, we will review lung patterns and distributions of common pulmonary diseases while putting the clinical picture together. Lung patterns are simply the radiographic appearance of diseases in the lungs. Therapy is mostly supportive. There are several reasons we take thoracic radiographs. Enlargement of the left atrium is the most common type of cardiomegaly identified radiographically. Main pulmonary artery enlargement as well as pulmonary hypertension, can be confirmed via echocardiography. Table 1. Less common causes for this appearance are masses, abscesses, or lung lobe torsion. If the patient does not respond to treatment within seven days, then airway sampling should be performed for cytologic evaluation, culture and Mycoplasma testing. The 7-8 o’clock position is the right ventricle and the 9:30-11:30 o’clock position is the right atrium. On the VD and DV images, the enlarged right ventricle appears more rounded and protrudes more into the right hemi-thorax, giving the cardiac silhouette a reverse D appearance. Le diagnostic final repose sur l'exclusion d'autres maladies respiratoires chroniques (imagerie: scanner pulmonaire-bronchoscopie), même s'il ne peut être formellement confirmé que par un examen histopathologique du tissu pulmonaire… ), que pour vérifier l’efficacité de son travail (La broche de mon chat est-elle bien en place ?)..

La lecture du cliché comporte successivement l'analyse des structures osseuses, des tissus mous, du médiastin, des champs pulmonaires. Important examples of radiographic lung patterns include the following: When we have a patient with a cranioventral interstitial or alveolar pattern, differential diagnoses include aspiration pneumonia, atelectasis, or hemorrhage or pulmonary thromboembolism. Deux chiens ont été présentés avec une volumineuse masse pulmonaire dont l’analyse cytopathologique confirma le diagnostic de mastocytome (MCT).

Wright-Giemsa stain; Magnification 1000×. If a diagnosis of PTE is made based on a predisposing condition, clinical signs and radiographic findings, then treatment should be initiated. Notice the increased apicobasilar dimension causing dorsal displacement of carina, enlargement of left atrium and auricle, and dorsolateral displacement of caudal bronchi. Non-cardiogenic pulmonary edema can occur secondary to airway obstruction, seizures, electrocution, vasculitis or acute lung injury/acute respiratory distress syndrome. It doesn’t show specific details of the heart and so only general changes in shape and size can be seen. The most common causative agents are B. bronchiseptica, S. equi subspecies zooepidemicus, and Mycoplasma spp. Otherwise, computed tomography is indicated for a definitive diagnosis.

Figure 9. Pulmonary venous distension occurs without arterial enlargement with cardiac volume overload (e.g. The patient was euthanized and histopathology confirmed a poorly granulated MCT with characteristics suggestive of epitheliotropism, an uncommon finding with MCT. Rounding, particularly in the area of the atria, can indicate cardiomegaly. Other common pathogens can be found concurrently. Papich, S.C. Rankin, J.E. If radiographs and clinical signs are consistent with feline asthma, the patient should be treated with anti-inflammatory doses of glucocorticoids. Are you a veterinary professional? Radiographically there is a diffuse bronchial pattern. It is important to include left and right lateral radiographs, as it may only be detectable on one side, depending on which lung is diseased. This is a self-limiting disease, but treatment can include cough suppressant and appropriate antibiotics such as Doxycycline. Figure 1. The cardiovascular consequences of PTE are dependent upon the degree of pulmonary vascular occlusion. is an agent identified in patients with diffuse pulmonary infiltrates.
