What are the signs and symptoms of bronchiolitis obliterans?

Bronchiolitis obliterans is characterized by a dry cough and shortness of breath which develop 2 to 8 weeks after toxic fume exposure or a respiratory illness. Fatigue and wheezing in the absence of a cold or asthma may also be noted.[1]

While high resolution chest CT scans and pulmonary function tests may help to detect bronchiolitis obliterans, a surgical lung biopsy is the most definitive way to diagnose the disease.[1]
