目的 评价空气支气管征鉴别诊断外周型肺孤立结节（直径≤３ｃｍ）的价值。方法 作者回顾分析了经手术或／和纤支镜或／和肺穿刺活检病理证实的１９０例外周型肺结节的空气支气管征的薄层ＣＴ影像。结果１００例肺癌ＣＴ显示空气支气管征５２例（５２％），其中腺７１％．９％（２２／３１）、鳞癌３４．１％（１４／４１）、腺鳞癌４／５、小细胞癌７／１４、低分化癌５／９。５０例炎性假瘤ＣＴ显示空气支气管征２９例（５８％）。３２例结核球、５例错构瘤及３例肺囊肿均无肺空气支气管征。结论 空气支气管征可见于多种结节性肺病变，它似乎不是外周型小肺癌尤其腺癌的特征。也不能帮助鉴别良恶性肺结节。
Objective To evaluate the value of differential diagnosis of bronchial airway in the diagnosis of isolated pulmonary nodules (diameter≤3cm). Methods The authors reviewed thin layer CT images of air bronchial signs in 190 cases of peripheral pulmonary nodules confirmed by surgery and / or bronchoscopy and / or lung biopsy. Results 100 cases of lung cancer CT showed air bronchial sign in 52 cases (52%), of which 71% of the gland. 9% (22/31), squamous cell carcinoma 34.1% (14/41), adenosquamous carcinoma 4/5, small cell carcinoma 7/14, poorly differentiated carcinoma 5 / 9.50 cases of inflammatory pseudotumor CT showed air Bronchial signs in 29 cases (58%). 32 cases of tuberculoma, 5 cases of hamartoma and 3 cases of pulmonary cysts were no lung air bronchogram. Conclusion Air bronchial signs are found in a variety of nodular lung lesions and appear to be not characteristic of peripheral small lung cancer, especially adenocarcinoma. It can not help identify benign and malignant pulmonary nodules.
