The first case is a 40-year-old male worker at an air conditioner management company. He was admitted to the hospital because of cough, fever and waterly diarrhea. Legionella pneumonia was suspected and EM and RFP were prescribed. After transient recovery, the disease recurred. CT-NAB was performed to establish diagnosis. Subsequently, pneumothorax and empyema developed. He died on the 57 th hospital day. The diagnosis was male based on the elevated serum antibody on the 27 th hospital day. The second case is a 49-year-old male public construction worker. He presented with fever. Legionella pneumonia was suspected. EM and RFP were prescribed with benefit. Legionella pneumophila was isolated from bronchial washing and sputum and the diagnosis was established.
