초록
호흡곤란과 기침을 주 증상으로 보이는 세마리 개가 내원하였다. 신체검사, 혈액검사와 더불어 영상학적 검사가 진행되었다. 한마리 개에서는 흉부 방사선 사진상 연부조직 밀도를 보이는 종괴가 폐엽에서 확인 되었고 CT 검사를 통해 종양 가능성이 배제되었다. 두마리 개에서 폐에 기관지 확장증이 동반된 기관지 간질 침윤이 확인되었고 세 마리 개 모두 조직병리학적 검사 혹은 세포학적 검사를 통해 호산구성 기관지폐병증이 진단되었다. 약 처방 후 임상 증상은 신속히 개선되었고 영상검사상에서 병변의 감소가 뚜렷하게 관찰되었다.
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.
