Abstract

A miniature pinscher and two Maltese dogs were present with dyspnea, and radiography and computed tomography (CT) were performed. All dogs were diagnosed with giant bullous emphysema of the massive, hyperexpanded, and hypoattenuating bulla causing contralateral mediastinal shift. Giant bullous emphysema, the rarest form of bullous lung disease, is defined as a bulla that fills more than 30% of the hemithorax, and multi-detector CT scanning could provide the useful information to confirm a diagnosis of giant bullous emphysema in older dogs. The radiographic and computed tomographic features for giant bullous emphysema were described.

12년령의 미니어쳐 핀셔 1 마리와 각각 8년령, 10년령의 말티즈 2 마리가 호흡곤란을 주증으로 내원하여 흉부 방사선 촬영과 다중검출기 컴퓨터단층촬영을 실시하였다. 컴퓨터단층촬영 시, 호흡의 고정을 위하여 양압환기를 실시하여 무호흡을 유발하였다. 3 증례의 컴퓨터단층영상에서 폐의 과확장된 거대한 낭포성 가스 종괴가 확인되었으며, 종괴에 의한 전종격동 및 심장의 변위가 확인되어, 거대 낭포성 폐기종으로 진단하였다. 거대 낭포성 폐기종은 낭포성 가스 종괴가 동측 흉강의 1/3 이상을 차지하는 것으로 정의되며, 다중검출기 컴퓨터단층촬영을 통한 진단으로 유용한 정보를 획득할 수 있다.
