Bronchial thermoplasty (BT) is a novel treatment for patients with severe asthma (1). Although respiratory adverse events such as asthma attack, atelectasis, and pneumonia are widely known as complications following BT (1), endobronchial organic lesions such as inflammatory bronchial polyps are not generally recognized as such by clinicians. We experienced a suspected case of an inflammatory bronchial polyp induced by BT that showed a spontaneous resolution. Written patient consent was obtained for this case report.
