12例支气管肺类癌的X线诊断

目的：分析支气管肺类癌的X线表现特点。方法：回顾性分析12例经手术病理证实的支气管肺类癌的X线平片及CT表现。结果：肺类癌为单发类圆形，边界清晰，密度均匀，多有分叶改变，转移少见，无钙化。CT像上肿块密度、边缘与相邻组织关系更为清晰。结论：支气管肺类癌缺乏X线特征，难与肺癌和肺部其它肿瘤性病变相鉴别，最后诊断需要病理证实。

X-ray diagnosis of bronchial carcinoid of lung in 12 cases

Objective:To study the X-ray manifestations of the bronchial carcinoid of lung.Methods:The manifestations of X-ray and CT in 12 patients with bronchial carcinoid of lung confirmed by operation and pathology were analysed retrospectively.Results:The carcinoid mass in lung presented as a single round or lobulated tumor in most cases,and appeared well outlined in boundary and homogenous in density,no calcification and less metastasis were found.CT showed that the density and margin of mass and its relationship with the adjacent structures were more clear.Conclusion:The bronchial carcinoid of lung was lack of specificity in X-ray features and could be poorly differentiated from bronchogenic carcinoma and other tumor of lung.The ultimate diagnosis should be confirmed by histopathology.
