A 44-year-old woman was admitted to our hospital because of a 15-month history of exertional dyspnea, nonproductive cough and fever. Thoracic high-resolution computed tomography (HRCT) showed centrilobular ground-glass opacities distributed in bilateral lung fields. She had worked at a down quilt factory and had been exposed to a large amount of feathers for 5 years. A peripheral lymphocyte proliferation test by positive was positive for pigeon serum. We diagnosed bird-related hypersensitivity pneumonia. After quitting her job, improvement of her clinical symptoms and chest imaging findings were observed and she has been free of relapse.
