| 【摘要】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。 |
| 【Abstract】Objective:To analyze the CT manifestations of small tracheal diverticulum,in order to improve the understanding 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 diverticula,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 diverticum (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 diverticulum 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. |
