A 51-year-old woman is brought to the emergency department because of an aggressive cough with copious amounts of thick, foamy, yellow-green sputum. She says she has had this cough for about 11 years with exacerbations similar to her presentation today. She also reports that her cough is worse in the morning. She was evaluated multiple times in the past because of recurrent bouts of bronchitis that have required treatment with antibiotics. She is a non-smoker. On physical examination, the blood pressure is 125/78 mm Hg, pulse rate is 80/min, respiratory rate is 16/min, and temperature is 36.7°C (98.0°F).

The chest X-ray shows irregular opacities in the right middle lobe and diffuse airway thickening. Based on this history and physical examination, which of the following is the most likely diagnosis?
