摘　　要：目的探讨肺孤立性病灶支气管改变的MSCT表现及其诊断价值。方法回顾性分析27例经病理或随访证实的肺孤立性病灶支气管改变的CT表现。结果CT显示支气管截断征14例(51.9%),其中周围型腺癌8例,鳞癌1例,腺鳞癌1例,恶性淋巴瘤1例,转移性恶性黑色素瘤1例,结核和炎性肉芽肿各1例;含气支气管征16例(59.3%),其中以腺癌最多见(10例);支气管在病灶边缘走行4例(14.8%),其中腺癌2例,肺泡癌1例,炎性肉芽肿1例;支气管受病灶牵拉移向病灶3例(11.1%),包括鳞癌1例,腺鳞癌1例,结核1例。结论MSCT能够很好地评价肺孤立性病灶的支气管改变,对肺癌的诊断和鉴别诊断有重要的临床价值。Objective： To investigate the multi-slice CT （MSCT） findings and the diagnostic value for the bronchial changes of the solitary pulmonary lesion. Methods：27 patients with pathology proved or follow-up diagnosed solitary pulmonary lesion underwent chest MSCT scanning, the findings were studied retrospectively. Results： Bronchial cut-off sign was demonstrated in 14 cases （ 51.9 % ）, including periphery adenocarcinoma （n = 8）, squmaous cell carcinoma （ n = 1 ） adenosquamous carcinoma （n= 1 ）, malignant lymphoma （n= 1）, metastatic malignant melanoma （n= 1） and inflammatory granuloma （n= 2） ;air bronchogram was shown in 16 cases （59.3 %）, in which adenocarcinoma （n= 10） predominated; bronchus ran along the margin of pulmonary nodule in 4 cases （14.8 % ） , with adenocarcinoma （n= 2）, bronchioloalveolar carcinoma （n= 1）, inflammatory granuloma （n= 1 ） ; bronchus dragged toward the pulmonary nodule in 3 cases （11. 1 %）, including squamous cell carcinoma,adenosquamous carcinoma and tuberculoma one case each. Conclusion：The bronchial changes within or adjacent to a pulmonary solitary lesion could be primely revealed by MSCT, which is clinically very helpful to the diagnosis and differential diagnosis of pulmonary carcinoma.
