目的：分析气管小憩室的CT表现，提高对本病的认识。方法：回顾性分析81例气管小憩室的CT表现及42例随访病例的CT改变。结果：81例气管小憩室均位于气管右后方6～7点处。81例气管小憩室中，类圆形75例，三角形3例，不规则形3例。81例共86个小憩室，其中单发者73例（73个），多发者8例（13个）。86个气管小憩室平均最大径为2．2mm。本组86个小憩室中64个可见开口与气管相通（64/86），41个窄开口使小憩室呈瓶颈样改变（41/64），23个宽开口使小憩室呈凹槽样改变（23/64）。42例随访病例的CT表现：小憩室消失1例，小憩室变大7例，小憩室生成7例，小憩室消失后再度出现3例。结论：CT能准确清晰显示气管小憩室的形态、位置、数目、大小和开口。典型的气管小憩室形态改变为烧瓶状和凹槽状。通过CT可观察到气管小憩室的发生、发展、消失及消失后再生的复杂过程。

Objective:To analyze the CT manifestations of small tracheal diverticulum,in order to improve the under-standing of this disease entity.Methods:CT manifestations of 81 patients with small tracheal diverticulum and the changes of 42 patients during follow-up were analyzed retrospectively.Results:All of the small tracheal diverticula were located at the posterior area of the right side of trachea (at the point of 6 to 7 o′clock).The morphology was round (n= 75),triangular (n= 3)and irregular (n= 3).Totally 86 small tracheal diverticula were assessed in these 81 cases,with single diverticulum in 73 cases (n= 3),and multiple in 8 cases (n= 13).The mean maximum diameter was 2.2mm.In 64 of 86 small diverticu-la,the openings communicating with tracheal lumen (64/86)were revealed,41 (41/64)with narrow opening (flask-like), and 23 (23/64)with broad opening (groove-like).Among the 42 cases with follow-up,there was disappearance of divertic-um (1 case),enlargement of the small diverticulum (7 cases),emerging of new diverticulum (7 cases),disappearance and then reappearance of diverticulum (3 cases).Conclusion:The shape,location,number,size and opening of small tracheal di-verticulum could be accurately and clearly displayed on CT.The typical manifestations are flask-shaped and groove-shaped. Also the complicate process of occurrence,development and disappearance as well as reappearance of the diverticulum could be observed on CT.
