title: [A case of non-invasive pulmonary aspergillosis that rapidly deteriorated].
abstract: The pulmonary diseases caused by the Aspergillus species include invasive forms, for example, invasive pulmonary aspergillosis, chronic necrotizing pulmonary aspergillosis, and non-invasive pulmonary aspergillosis. Though these forms are defined pathologically by the presence of the Aspergillus species that invades the lung tissue, they are used as clinical entities. We report a case of non-invasive pulmonary aspergillosis which, from the clinical data, appeared likely to be misdiagnosed as the chronic invasive form. A 45 year-old man received chemoradiotherapy for lung cancer as well as undergoing an left upper lobectomy. Two weeks after the surgery the patient developed a cough, high fever and chest pain. Chest radiography and chest computed tomography showed a rapidly enlarging cavity with an internal mass and infiltration in the left lower lung field. A transbronchial biopsy specimen of the cavity wall showed fungal hyphae. Bronchial washing culture grew Aspergillus fumigatus. Itraconazole and amphotericin B were administered, but the patient's condition did not improve. A left lower lobectomy was performed. The histologic findings showed that the fungal hyphae were only on the surface of the cavity wall, and were surrounded by necrosis and widespread inflammatory cell infiltration. No fungal invasion of the viable lung tissue was seen. The area of infiltration revealed an organizing pneumonia without Aspergillus or other organisms. Our final diagnosis was non-invasive pulmonary aspergillosis. There has been no recurrence of the lung cancer or of the pulmonary aspergillosis in the three years since surgery. It is reported that non-invasive pulmonary aspergillosis passes through a period so active that it seems to be the invasive form for its entire clinical course. To avoid confusion in diagnosis, establishment of a comprehensive clinical classification of pulmonary aspergillosis will be needed.
