Imaging Diagnosis-Pulmonary Interstitial Emphysema in a Dog

In humans, pulmonary interstitial emphysema is most frequently seen in ventilated preterm newborns with severe lung disease; it is less frequently reported in adults. We report on a mature dog with pneumopathy that underwent computed tomography (CT) imaging to further characterize the lung disease. A bronchiolar pattern and lobar opacification were seen on the CT images. Moreover, gas was detected along the course of the pulmonary vessels, presumably in the interstitium, as seen in pulmonary interstitial emphysema in humans. Sever lung disease and/or hyperventilation during anesthesia could be a possible explanation of pulmonary interstitial emphysema in this dog.
