[A case of chronic necrotizing pulmonary aspergillosis]

A 70-year-old woman with diabetes mellitus who was following a therapeutic diet showed an infiltrative shadow in the right upper lung field on chest roentgenogram in April, 1986. She was diagnosed as having pneumonia and was treated for five months with several antibiotics, but the abnormal shadow on chest roentgenograms increased in size. Therefore, she was admitted to our hospital in October 1986. Although tubercle bacilli were not isolated from her sputum or from materials obtained by bronchoscopic examination, we made an initial diagnosis of pulmonary tuberculosis based on the findings of chest roentgenograms, tomographs and CT scanning. In spite of treatment with antituberculous drugs, the infiltrative shadow with cavity on chest roentgenograms continued to increase in size, and the patient developed occasional hemoptysis. Percutaneous needle biopsy was performed in February 1987 to establish a definite diagnosis, and the presence of Aspergillus fumigatus was confirmed by microscopic examination and culture. After treatment with miconazole and 5-FC for 3 to 4 months, the abnormal shadow on the chest roentgenogram gradually disappeared and was almost undetectable one year later. The clinical course of this patient was considered to be strongly indicative of chronic necrotizing pulmonary aspergillosis, which was described by Binder et al. in 1982.
