Aspergillus-associated pulmonary diseases are aspergilloma, invasive aspergillosis, and allergic bronchopulmonary aspergillosis. Allergic bronchopulmonary aspergillosis is caused by a complex of immunologic reactions to the presence of the Aspergillus species colonizing the bronchial trees. The disease is not common in Taiwan. The major diagnostic criteria for allergic bronchopulmonary aspergillosis are 1) bronchial asthma, 2) pulmonary infiltration, 3) peripheral eosinophilia, 4) positive skin test to Aspergillus fumigatus, 5) serum precipitin to Aspergillus fumigatus, 6) elevated serum Ig E, and 7) central bronchiectasis. We report a case who has had a chronic asthmatic-like cough for 5 years. He worked in a silo for two years before he was troubled by the disease. He was admitted to hospitals four times in the past, and received five bronchoscopic examinations and one open lung biopsy without definite diagnosis. Sputum eosinophilia directed our attention to the differentiation of eosinophilic lung diseases. A bronchogram which revealed central brochiectasis helped us to make the diagnosis of allergic bronchopulmonary aspergillosis, despite negative sputum culture for Aspergillus fumigatus and negative serum precipitin to Aspergillus fumigatus.
