肺癌部分性或完全性阻塞支气管时,在X线平片上常引起远侧肺的密度增高阴影。临床上它更是中央型肺癌的最初的X线表现之一,值得重视。自1949年Mc Dooald首次提出阻塞性肺炎名称以来,一直认为它是受侵肺的支气管内分泌物潴留后细菌继发感染所致。本文收集经手术、内镜、或分层、痰检证实的中央型肺癌180例,就胸部平片上呈现的X线表现进行分析发现:被阻塞支气管远端肺除有实变阴影外,尚有间质纤维增生,间质
When lung cancer partially or completely blocks the bronchus, the X-ray film often causes an increase in the density of the distal lung. Clinically, it is one of the first X-ray features of central lung cancer and deserves attention. Since McDooald proposed the name of obstructive pneumonia for the first time in 1949, it has been thought that it was caused by a secondary bacterial infection after the retention of the bronchial secretions of the lung. This article collected 180 cases of central lung cancer confirmed by surgery, endoscopy, or stratification and sputum examination. The analysis of the X-ray findings on chest plain films revealed that except for the obstructed bronchial distal lung, in addition to consolidation shadows, there were Interstitial fibrosis, interstitial
