ABSTRACT
Despite treatment for aspirin-induced asthma for 27 years, a 57-year-old male suffered repeated attacks. He recently underwent a series of bronchial thermoplasty (BT) sessions for refractory asthma at our hospital. A pulmonary cyst containing fluid appeared in the middle lobe of the right lung the day after the third BT session. The cyst was not treated because there were no signs of infection, and it began to shrink over time. In our view, possible causes of the cyst include mucus plugs, a change in part of the airway caused by the high-frequency stimulation of BT having resulted in a one-way valve, or laceration of the lung by the thermal energy from BT.
