摘　　要：目的:分析老年人气管支气管结核的CT表现。方法:回顾性分析46例老年人支气管结核患者CT及临床资料,其中15例经病理学证实,5例经细菌学证实,26例经临床抗结核治疗有效证实。结果:①46例共检出98支病变,两肺上叶为结核好发部位(40/98,40.8%),多支受累为其特点(32/46,69.6%)。②CT特征表现为支气管不规则或规则狭窄及梗阻,部分显示管壁增厚及管腔内结节。③间接征象为肺内多发结核灶,肺叶、肺段不张或(和)实变,肺门纵隔淋巴结肿大。结论:CT能较好显示气管支气管结核的特征,结合临床及FOB检查可提高诊断准确性。Objective： To study the CT features and increase the diagnostic capability in aged patients with tracheobronchial tuberculosis （tTB）. Methods： Forty-six aged patients with tTB underwent CT were reviewed retrospectively. Among which, 15cases were confirmed by biopsy, 5 cases were confirmed by bacteriology and 26 cases were confirmed by clinical follow up findings. Results： （1） There were 98 lesions in 46 cases, 40 of 98 lesons were found in upper lobes of the bronchi （40.8%）. 69.6% of the cases had multiple involvement of 2 or more bronchi. （2） To demonstrate thickening of the bronchial wall or intraluminal tubercle and irregular or smooth stenosis or obstruction were the main direct signs of tTB. （3） The indirect signs of tTB were lungparenchymal TB, collapsed and （or） consolidated lung segment or lobe and enlarged hilar or mediastinal lymph nodes. Conclusions： CT is a valuable diagnostic procedure to reveal tTB.
