摘　　要：目的探讨气管支气管巨大症的l临床诊断及治疗，提高对气管支气管巨大症的认识。方法分析气管支气管巨大症的临床特点、影像学表现、纤维支气管镜特征及临床诊断，并复习相关文献。结果患者以反复咳嗽、咳黄脓痰、阵发性胸闷气促为特点，胸部CT检查显示气管、左右主支气管直径明显增大，纤维支气管镜下显示气管、支气管管腔扩张，软骨显露明显，憩室形成。结论气管支气管巨大症临床罕见，常规X线胸片检查容易漏诊，反复发生下呼吸道感染的患者应行胸部CT检查协助诊断。Objective To enrich our experience with tracheobronch6megaly （TBM） and to improve the diagnosis and treatment for TBM in the clinical settings. Methods One case of TBM was reported. The clinical manifestations, radiographic features, fiberoptie bronchoscopy findings were investigated and the related literatures were comprehensively reviewed. Results The patient was characterized by recurrent productive cough with infected sputum, paroxysmal chest tightness and shortness of breath. Chest computed tomography （CT） demonstrated the enlargement of the diameter of the trachea and right and left main bronchi. Fiberoptic bronchoscopy revealed a dilated tracheobronchial with prominent tracheal rings, and multiple diverticula between the cartilaginous rings in the beginning of the right and left main bronchi. Conclusions TBM is a very rare disorder. The misdiagnosis may occur if it is only made on plain films chest X-ray. Patients who have recurrent lower respiratory infections should have a CT scan to assist in making the diagnosis.
