A 59-year-old male smoker presented with persistent wheezing and occasional coughing that had been ongoing for two years and had been unsuccessfully treated with an inhalational β2 agonist, an anticholinergic and an inhalational steroid in the last year. On clinical examination, a left-sided wheeze was detected. The initial chest X-ray was normal.
