摘　　要：目的 探讨原发性气管及主支气管肿瘤影像学检查价值。方法回顾性分析33例经病理证实的原发性气管及主支气管肿瘤影像资料，并与手术、病理进行对照。结果气管及主支气管肿瘤位于气管上段3例，中段9例，下段14例，气管隆突1例及主支气管6例。本组通过影像学检查显示为良性肿瘤9例，恶性肿瘤24例，和手术及病理改变相一致。影像学表现可分为以下几种：（1）宽基底管腔内结节；（2）窄基底管腔内结节；（3）管腔外肿块。本组27例根据胸片表现导致漏、误诊有4例，22例根据CT表现导致漏、误诊有3例。结论影像学检查对原发性气管、主支气管肿瘤的检测具有重要意义。Objective To discuss the values of imaging examinations in primary tracheal and main bronchial tumors. Methods Imaging data of 33 cases with primary tracheal and main bronchial tumors confirmed by pathology were retrospectively analyzed and compared with that of operation and pathology. Results 33 cases with primary tracheal and main bronchial tumor were accurately located by imaging including tracheal upper segment in 3 cases, middle segment in 9 cases,lower segment in 14 cases, tracheal protuberance in 1 case and main bronchi in 6 cases. The imaging examinations showed benign tumors in 9 cases, malignant tumors in 24 cases were coincided with that of operation and pathology. The imaging findings included ： （ 1 ） Intralumen tubercle node with wide fundament; （ 2）Intralumen tubercle node with narrow fundament; （3）Extrolumen mass. 4/27 cases were misdiagnosed by chest X-ray films and 3/22 cases were misdiagnosed with CT scan. Conclusion Imaging examinations are of significant value in detecting primary tracheal and main bronchial tumors.
