支气管气像的影像学分析

Imaging analysis of air bronchogram

目的探讨支气管气像的影像学特征。方法回顾性分析65例支气管气像的影像学表现。结果支气管气像可见于肺部感染性或非感染性病变。肺部感染性病变43例,包括大叶性肺炎21例,球形肺炎1例,支原体肺炎6例,干酪性肺炎7例,支气管结核3例,真菌感染5例。非感染性病变22例,包括支气管扩张8例,肺挫伤6例,肺水肿4例,肺癌2例,肺淋巴瘤1例,尘肺1例。结论支气管气像的病因多样化,影像学检查对探及病因有一定的作用。

Objective To evaluate imaging findings of air bronchogram. Methods Imaging findings of bronchogram air with cases were analyzed retrospectively.Results Air bronchogram may secondard to pulmonary infectious(n =43) or non-infectious diseases(n =22).Etiologies of pulmonary infectious diseases included lobar pneumonia(n=21),spherical pneumonia(n=1),mycoplasma pneumonia(n=6),cheesypneumonia(n=7) and bronchial tuberculosis(n=3),pulmonary fungal diseases(n=5). Non-infectious diseases included bronchiectasis(n=8),pulmonary contusion(n=6),pulmonary edema(n=4), pulmonary carcinoma(n=2), pulmonary lymphoma(n=1),and pneumoconiosis(n=1).Conclusion Etiologies of air bronchogram are varied. Thoracic DR and and CT may used in detection of etiology of air bronchogram.
