Abstract

A 9-year-old, castrated male Malamute dog was presented with chronic cough. On thoracic computed tomography, non-tapered and dilated peripheral bronchi were detected. Bronchoarterial ratio was about 2.2. The dilated bronchi appeared as a cluster of grapes especially in left cranial, left caudal and right middle lung lobe. Based on the computed tomographic findings, the diagnosis was made as the saccular type of bronchiectasis.

9년령의 중성화한 말라뮤트가 만성 기침 증상으로 내원하였다. 흉부 컴퓨터단층촬영상에서 말초 기관지가 확장된 모습으로 관찰되었다. 기관내강과 폐동맥 직경 비율은 약 2.2로 정상보다 큰 비율을 나타내었다. 확장된 기관지들은 특히 좌측 전엽과 후엽, 우측 중엽에서 포도송이 모양과 같은 형태를 보였다. 이러한 컴퓨터단층촬영 소견들을 바탕으로 낭상 기관지 확장증을 진단하였다.
