PURPOSE
The purpose of this article is to describe the radiologic findings to diagnose congenital bronchial atresia.
METHODS
Chest radiographs, CT scans, and MRI of nine patients with congenital bronchial atresia were reviewed.
RESULTS
Six patients (67%) had hilar mass-like shadows and hyperlucency of the peripheral lung field on chest radiographs. On chest CT scans, all patients demonstrated mucocele, occlusion of bronchus central to mucocele, and emphysematous change of the peripheral lung field. On chest MRI, performed in seven patients, all mucoceles demonstrated very high signal intensity on T2-weighted image, indicating that mucoceles were filled with fluid.
CONCLUSION
Diagnosis of congenital bronchial atresia can be confirmed based on the findings of chest CT: mucocele, occlusion of bronchus central to mucocele, and emphysematous change of the peripheral lung field.
目的
本文旨在描述诊断先天性支气管闭锁的放射学表现。
方法
回顾了9例先天性支气管闭锁患者的胸部X线片、CT扫描和MRI检查结果。
结果
6例（67%）患者胸部X线片显示肺门肿块样阴影及外周肺野透亮度增加。胸部CT扫描显示，所有患者均有黏液囊肿、黏液囊肿近端支气管闭塞及外周肺野肺气肿改变。7例患者进行了胸部MRI检查，所有黏液囊肿在T2加权像上均表现为极高信号强度，提示黏液囊肿内充满液体。
结论
根据胸部CT表现：黏液囊肿、黏液囊肿近端支气管闭塞及外周肺野肺气肿改变，可确诊先天性支气管闭锁。
