After infancy the most common presentation is with repeated or prolonged episodes of pneumonia despite adequate antibiotic coverage.The infectious course arises because the contents of the cyst do not communicate with the tracheobronchial tree,allowing bacteria and debris to accumulate in the cyst.This material cannot be evacuated and acts as a nidus for infection,which often spreads to adjacent healthy tissue and lymph nodes in the hilum of the involved lung.Thus,a small infected cyst can result in pneumonia with fever and purulent cough.Although antibiotics are helpful,they are not curative,and the underlying cause,that is,the cyst,must be resected to prevent recurrence of pulmonary infections.
