摘　　要：目的探讨支气管内膜结核与中央型肺癌的CT诊断及鉴别诊断。方法回顾性分析48例经临床、病理证实的病例,总结其CT特征及鉴别要点。结果48例中,21例支气管内膜结核;27例中央型肺癌,其中鳞癌20例,小细胞癌7例。支气管狭窄、腔内结节、管壁增厚僵直且累及支气管段较长,不伴受累支气管周围肿块形成,肺不张与阻塞性肺炎内见支气管扩张或(和)空洞、钙化等强烈提示支气管内膜结核,而支气管狭窄段较短,管壁明显增厚或伴受累支气管周围软组织肿块形成,不张密度均匀一致等则提示中央型肺癌。结论CT对支气管内膜结核与中央型肺癌的鉴别诊断有一定的价值。Objective To study CT diagnosis and differential diagnosis of endobronehial tuberculosis and central lung cancer. Methods CT features and differential diagnosis in 48 cases with pulmonary lesions confirmed by clinical and pathology were analyzed retrospectively. Results Of 48 cases, 21 cases were endobronchial tuberculosis and 27 cases were central lung cancer including 20 cases of squamous cell carcinoma and 7 cases of small -cell lung cancer. On CT, showing bronchiartia, nodules inside the lumen, the bronchial walls thickened, bronchus involved longer, not accompanied with masses around the affected bi＇onchus, atelectasis and obstructive pneumonia with the bron- chiectasis or cavities and calcification, which were strongly promised the endobronchial tuberculosis. And it pointed out the central lung cancer if bronchiartia was shorter, the bronchial walls were thickened clearly and accompanied with masses around the affected bronchus and atelectasis with homogeneous density. Conclusion CT is of certain value in diagnosis and differential diagnosis of endobronchial tuberculosis and central lung cancer.
