Abstract

Aspiration is defined as accidental entrance of foreign matter into the lower respiratory tract, and is a common event and can occur in healthy individuals. The type of aspiration-induced lung diseases depends on the quantity and nature of the aspirated material, the chronicity, and the host responses. Aspiration into the airways and lungs can cause a wide spectrum of lung diseases with various manifestations in adults. Diseases with predominantly airway manifestation include foreign body aspiration and diffuse aspiration bronchiolitis. Diseases with predominantly lung parenchymal manifestation include acute diseases such as aspiration pneumonia, aspiration pneumonitis, and near drowning, and chronic diseases such as chronic exogenous lipoid pneumonia and chronic interstitial lung disease. Definitive diagnosis of aspiration-induced lung diseases is challenging to make. Awareness of radiologic findings associated with these diseases is essential for accurate diagnosis and management of these diverse aspiration-induced lung diseases.

흡인은 우발적으로 하부 호흡기로 이물질이 유입되는 것으로 정의한다. 흡인은 흔히 발생하며, 건강한 성인에게도 발생할 수 있다. 흡인으로 인한 폐질환의 유형은 흡인한 물질의 성분과 양, 만성도, 흡인한 물질에 대한 숙주의 반응에 따라 달라진다. 성인에서 흡인은 다양한 임상 증상과 함께 다양한 폐 질환을 유발할 수 있다. 영상의학적으로 진단할 수 있는 흡인관련 폐질환 중 기도가 주 병소인 질환으로는 기관기관지 이물과 미만성흡인세기관지염이 있다. 폐실질이 주 병소인 질환으로는 급성 질환인 감염성흡인폐렴, 비감염성흡인폐렴, 익사 직전 폐와 만성 질환인 만성외인성지질폐렴과 만성간질폐질환이 있다. 흡인 관련 폐질환의 진단은 종종 어려울 수 있으며, 정확한 진단과 적절한 치료를 위해 영상의학소견에 대한 지식은 필수이다.
