Patients present with a chronic or recurrent cough, which can be dry and hacking at the beginning and can produce mucoid (early) and purulent (later) sputum. Prolonged symptoms of bronchiolitis occur in infants. Paroxysmal cough followed by vomiting may occur.

Recurrent wheezing, recurrent pneumonia, atypical asthma, pneumothorax, hemoptysis, and digital clubbing are all complications and may be the initial manifestation. Dyspnea on exertion, history of chest pain, recurrent sinusitis, nasal polyps, and hemoptysis may also occur.
