Abstract

Pulmonary fibrosis (PF) is defined as a gradual, interstitial fibrous disease of the lung parenchyma. PF causes collapse of the lung lobe, which can lead to lung lobe torsion of the other side. A 14-year-old male Pekinese dog was referred to the Veterinary Medical Center, Chungbuk National University. The chief complaint was acute dyspnea. The dog had a history of chronic cough, which lasted for 18 months, and the cough had recently deteriorated. Tachypnea was observed on physical examination. As a result of thoracic radiographs, ultrasonography, and computed tomography, lung lobe torsion and collapse were diagnosed. A postmortem examination revealed lung lobe torsion of the left cranial lobe and carnification of the right cranial lobe. Histologically, severe and diffuse interstitial fibrosis with distortion of alveolar architecture and severe congestion and/or hemorrhage were observed in the right cranial lobe and left cranial lobe, respectively. Although the cause of pulmonary fibrosis was undetermined, this case showed a typical lung lobe torsion caused by pulmonary fibrosis.
