[A case of broncho-pulmonary aspergillosis complicated by bronchial asthma attack]

A 55-year-old man was hospitalized for the treatment of severe asthma. However, his condition improved with steroid chemotherapy under artificial ventilation, but high fever and multiple patchy shadows of the lung that were not responsive to antibiotics appeared. We detected aspergillus hyphae, probably inhaled with a quantity of dust in the attic of his workplace, in the sputum. We diagnosed invasive broncho-pulmonary aspergillosis complicated with allergic broncho-pulmonary aspergillosis. His condition improved with anti-fungal drug treatment. We consider that the causes of invasive broncho-pulmonary aspergillosis in this case were massive inhalation of aspergillus conidia, artifical ventilation and steroid chemotherapy.
