INTRODUCTION: Bronchial thermoplasty (BT), which involves the delivery of radio frequency energy to the bronchial tree to reduce airway smooth muscle quantity and contractility, has been latterly bring in the treatment of severe refractory asthma. Follow-up data to date support the safety of the procedure. Atelectasis and Lung abscess after BT in severe asthma has been described in literature, but bronchiectasis has never been reported as a direct complication of BT.

CASE PRESENTATION: A forty nine year old Asian male has 2 years serve asthma, accompanied diabetes mellitus. His several times of chest CT scan is normal before BT. A month after BT he presented mild bronchiectasia in HRCT with yellow purulent sputum. After 3 months treatment with prednisone 10mg daily and Symbocort (4.5ug/160ug) 2 puff twice a day, expectorants and controlling glucose levels, his symptom improved and the chest CT scan returned to normal.

DISCUSSION: It can be hypothesized that intense thermal stimulation of the bronchial mucosa may cause the recurrence of bronchial inflammation, infection and plugging in susceptible patients, especially with diabetes mellitus, and then attribute to the the form of central bronchiectasis.

CONCLUSIONS: It remains unclear why this patient developed bronchiectasia after BT treatment. As the procedure becomes more widely available, It is important to pay attention for the short-term and long term safety data post BT treatment.
