ABSTRACT
A 58-year-old male race pigeon breeder gave up smoking in January 2011. On March 2011, a high-resolution CT scan showed ground-glass attenuation in his lung. He was admitted to Jichi Medical University Hospital in October 2013 for treatment of a productive cough. On admission, the results of video-assisted thoracoscopic surgical lung biopsy showed lymphocyte infiltration in respiratory bronchioles and alveolar septa. The day after discharge, he cleaned out his pigeon house. He became feverish, his productive cough worsened and his inflammatory markers elevated. We diagnosed bird-related hypersensitivity pneumonitis. He was treated with prednisolone and advised to quit pigeon breeding. The symptoms have not recurred since. This is an interesting case in which smoking cessation appears to have revealed underlying bird-related hypersensitivity pneumonitis.
