摘要

先天性肺葉氣腫乃由於支氣管阻塞形成活瓣效應，導致肺葉過度擴張。胸部X光片通常見到一過度透氣的區域，但若有肺液積留，則此區域變得不透明。後者的電腦斷層掃描及超音波表現，文獻上甚少提及。此篇報告一新生兒罹患先天性肺葉氣腫合併肺液積留，並描述其電腦斷層掃描及超音波發現－在電腦斷層掃描見到的是一囊狀腫瘤，超音波檢查才能呈現其實體的性質。

Congenital lobar emphysema (CLE) is thought to be a result of obstruction of the bronchus which causes air-trapping and overinflation of lung segments or lobes. It usually presents as a hyperlucent region on chest radiography. However, if there is accompanying retention of lung fluid, the affected region becomes opaque. Of such a lesion, the computed tomography (CT) scans or ultrasonographic findings have been rarely mentioned in the literature. We report the CT and echographic findings of CLE with retained lung fluid in a newborn. The lesion presented as a cystic mass on CT; ultrasonographic examination demonstrated its real solid contexture.
