摘　　要：目的:探讨原发性气管支气管腺样囊性癌的CT表现,提高术前诊断率。方法:回顾性分析12例经病理证实的原发性TACC CT影像资料,其中4个CT平扫加增强,1个CT平扫加CT增强加PET-CT,4个仅做了CT增强,2个仅做了CT平扫,1个CT平扫加PET-CT。结果:2个气管颈段;2个位于气管胸段;1个位于气管分叉;1例位于主支气管远端,累及隆突及左右支气管;2个位于左主支气管;1个位于中间支气管;2个位于左肺上叶支气管;1个位于右肺上叶支气管。CT表现:5例呈腔内宽基底型;2例呈管壁浸润型;5例呈腔内外生长型。结论:原发性TACC发病率低,临床表现无明显特异性,CT表现具有特征性诊断,主要依靠病理组织学,经手术治疗者预后较好。Objective: To explore the CT findings of primary tracheobronchial adenoid cystic carcinoma to im-prove the preoperative diagnosis rate. Methods: A retrospective analysis of 12 pathologically con-firmed primary TACC CT imaging data was performed, including 4 CT non-contrast scan plus en-hancement, 1 CT non-contrast scan plus CT enhancement plus PET-CT, 4 CT enhancement only, 2 CT non-contrast scanning, and 1 CT non-contrast scan plus PET-CT. Results: 2 tracheal neck segments;2 located in the tracheothoracic segment;1 located at the bifurcation of the trachea;one case was located at the distal end of the main bronchi, involving the carina and left and right bronchi;2 lo-cated in the left main bronchi;1 located in the middle bronchi;2 located in the bronchi of the upper lobe of the left lung;1 located in the bronchi of the upper lobe of the right lung. CT manifestations: Five cases were intraluminal with wide substrate type;two cases were infiltrated by the tube wall;five cases showed intraluminal and extravascular growth. Conclusions: The incidence of primary TACC is low, the clinical manifestations are not obvious, the CT manifestations have a characteristic diagnosis, mainly relying on pathological histology, and the prognosis of patients treated by surgery is good.
