Bronchial atresia (BA) is a rare congenital anomaly that is found incidentally in approximately 50% of cases. It predominantly affects young men and generally produces no symptoms. The other 50% of cases have pulmonary symptoms such as fever, cough, or shortness of breath due to recurrent pulmonary infection or overinflation of the involved lung parenchyma. The most common site is the left upper lobe, particularly of the apical-posterior segment. The right lower and middle lobes are affected in only 8% of cases. The radiographic features may be highly suggestive of the diagnosis. The mucus-filled bronchus is seen as a rounded, branching opacity emanating from the hilum and is surrounded by an area of increased hyper-translucency. We report an unusual presentation of BA in a 43-year-old woman with a history of recurrent pulmonary infection and dyspnea. The patient was found to have BA in all the basal segments of the lower lobe of the right lung.
支气管闭锁（BA）是一种罕见的先天性异常，约50%的病例为偶然发现。它主要影响年轻男性，通常不产生症状。另外50%的病例有肺部症状，如因反复肺部感染或受累肺实质过度充气导致的发热、咳嗽或呼吸急促。最常见的部位是左上叶，尤其是尖后段。右下叶和中叶仅8%的病例受累。影像学特征可能高度提示诊断。充满黏液的支气管表现为从肺门发出的圆形、分支状不透光区，周围是透亮度增加的区域。我们报告了一名43岁有反复肺部感染和呼吸困难病史的女性BA的不寻常表现。该患者被发现右肺下叶所有基底段均有BA。
