초록

폐염전으로 진단한 소형견 4 마리의 흉부 방사선 사진 및 컴퓨터단층촬영 (CT) 영상을 평가하였다. 흉수 및 폐염전이 발생한 폐엽의 밀도 증가는 4 마리 환자의 흉부 방사선 사진 및 CT 영상에서 모두 확인되었다. 폐염전이 발생한 기시부에서의 기관지의 협착/허탈은 CT 영상을 통해 4 마리의 개에서 모두 확인된 반면, 흉부 방사선 사진에서는 오직 1 마리의 환자에서만 확인되었다. 폐포성 폐기종 패턴 (vesicular emphysema pattern) 역시, CT 영상을 통해 4 마리의 환자에서 모두 확인된 반면, 흉부 방사선 사진에서는 3 마리에서 관찰되었다. 폐염전의 특이소견은 폐포성 폐기종 패턴과 폐염전이 발생한 폐엽 기시부의 기관지의 협착/허탈이며, 이 소견은 흉부 방사선 사진보다 CT 영상을 통해 좀 더 용이하고 빈번하게 확인되었다.

This case study describes the imaging features of radiography and computed tomography (CT) in four small breed dogs with lung lobe torsion. The medical records, thoracic radiographs and CT images of four dogs with confirmed lung lobe torsion were retrospectively reviewed. Pleural effusion and increased lobar opacity/density were seen on all CT and thoracic radiography in all four dogs. CT revealed narrowed/collapsed bronchus in all four dogs, while this was only appreciated on one thoracic radiography. The vesicular emphysema pattern was seen on four CT but only on three radiographic examinations. The specific findings of lung lobe torsion were vesicular emphysema and a narrowed/collapsed bronchus. These findings were more easily recognized on CT than with thoracic radiographs.
