支气管黏液嵌塞的CT诊断

CT diagnosis of bronchial mucoid impaction

目的探讨支气管黏液嵌塞的CT表现及其诊断价值。方法回顾性分析经临床及支气管镜确诊的18例支气管黏液嵌塞的CT表现。结果 CT显示支气管黏液嵌塞呈指套状11例(61.1%)、短管状3例(16.7%)、葡萄状4例(22.2%)。MPR显示指套状11例,10例增强扫描黏液栓均无强化,7例病灶周边见肺动脉及其分支伴行。结论 "指套征"为支气管黏液嵌塞的较特征性CT表现,正确认识其特点,有利于提高诊断的准确率。

Objective To explore the imaging features and diagnostic significance of CT in bronchial mu-coid impaction. Methods CT data of 18 cases with bronchial mucoid impaction diagnosed by clinic and broncho-scope were retrospectively analyzed. Results CT showed finger-in-glove sign in 11 cases （61.1%）, short tubular in 3 cases （16.7%）, and grape-like sign in 4 cases （22.2%）. The finger-in-glove sign in 11 cases was also observed in MPR images. Bronchial mucoid impaction showed no enhancement in 10 cases. 7 cases were accompanied with pulmonary arteries and its branches around. Conclusion The finger-in-glove sign is the character of bronchial mucoid impac-tion in CT findings. To correctly understand its characteristics can improve the accuracy of diagnosis.
