Imaging Features of Eosinophilic Bronchopneumopathy in Three Dogs

다국어 초록 (Multilingual Abstract)

Three dogs were presented with a history of dyspnea and cough. Physical examination, blood analysis,bronchoalveolar lavage and radiography of three dogs were evaluated. And additionally, computed tomography and lung biopsy were performed on one dog. They showed normal laboratory examination results. The radiographic findings noted alveolar and bronchointerstitial infiltration with bronchiectasis. For one dog, nodules scattered throughout both lung fields on survey radiographs were confused with pulmonary neoplasia, so CT scan was used to rule out neoplasia.
Bronchoalveolar lavage revealed abnormally high levels of eosinophils in all dogs. On histopatholgic exam, eosinophilic bronchiolitis and eosinophilic and histiocytic alveolitis were confirmed. Consequently, all dogs were diagnosed as eosinophilic bronchopneumopathy. Symptoms regressed dramtically within a few days after treatment with oral corticosteroids. Radiographs and CT scan are useful for diagnosis and prognosis of eosinophilic bronchopneumopathy.
