胸廓入口区气管旁含气囊肿的CT及临床表现 |
|
见肺纹理并与胸腔内肺组织相连[13],而本病虽在呼吸周期中其大小可稍有改变,但很少有完全消失不见者,并且距肺尖较肺尖疝及肺尖部间隔旁肺大疱为远,也很少有能压迫气管变形者。喉、咽囊肿可根据位置较本病高,胃镜、食管钡餐、纤维气管镜可见到与喉、咽的交通而得到诊断[14]。位于气管后方的本病和食管囊肿的鉴别较困难,有时囊肿内出现的气液平面可提示为食管囊肿,确诊还需依靠食管造影[15]。 综上所述,胸廓入口区气管旁右后外侧含气囊肿(部分囊肿可见与气管相连通)是气管憩室的典型征象,同时,在CT平扫上,气管憩室认为是临床上COPD和影像上肺气肿的可靠表现。并且在CT上气管囊肿和气管憩室的鉴别是十分困难的。气管憩室多发生在气管后壁,确诊还需依靠气管造影。 【参考文献】 [1]INFANTE M, MAUAVELLI F, VALENTE M, et al.
