摘　　要：目的探讨气管憩室最佳检查方法、影像表现及主要鉴别诊断。材料与方法搜集我院最近五年3例胸部平片或颈椎片见气管旁异常积气的患者,再行16层螺旋CT进一步检查证实为气管憩室的病例。同时分析我院5400例胸部16层螺旋CT扫描患者影像资料,发现气管憩室26例,其中13例经支气管镜或手术证实。从中总结气管憩室的影像表现及主要鉴别诊断。结果 26例气管憩室均表现为气管旁为不规则(或规则)含气空腔,并与气管缺损处相通。主要表现形式有:囊状8例;不规则状18例。发现最小憩室约2×5mm。气管憩室在多层螺旋CT扫描的发现率约为48/万。结论气管憩室并不少见,多层螺旋CT(MSCT)是发现气管憩室的最好方法,能发现较小的气管憩室,并有一定的影像特征。Objective To explore the best inspection methods, imaging findings and differential diagnosis of tracheal diverticulum. Material and Method To collect three cases of paratracheal abnormal gas accumulation for chest or cervical radiography in our hospital last five years, which confirmed tracheal diverticulum by 16-slice CT, meanwhile 26 cases of tracheal diverticulum were found in 5400 cases of 16-slice CT chest scan in our hospital, of which 13 were confirmed by bronchoscopy or surgery. From above we concluded the imaging findings and the main differential diagnosis of tracheal diverticulum. Result 26 tracheal diverticulum showed irregular paratracheal gas-containing cavity and connected to the tracheal defect. The main manifestations： 8 cases of cystic~ irregular shaped inl8 cases. Minimum diverticulum was found about 2 × 5mm. Tracheal diverticuinm was discovered in the rate of 48/10000 by multi-slice spiral CT scan. Conclusion Tracheal diverticulum is not uncommon. Multi- slice spiral CT is the best method to found tracheal diverticulum which can find smaller tracheal diverticulum, and have a certain image features.
