阻塞性肺病支气管扩张症。当出现阻塞和炎症感染时，引起永久性支气管扩张。一旦出现扩张的支气管，就如图肺中下部所见。反复感染、咳大量脓痰是其特征。
This is another form of obstructive lung disease known as bronchiectasis. Bronchiectasis occurs when there is obstruction or infection with inflammation and destruction of bronchi so that there is permanent dilation.Once the dilated bronchi are present, as seen here grossly in the mid lower portion of the lung, the patient has recurrent infections because of the stasis in these airways. Copius purulent sputum production with cough is typical.
