18-year-old man presented with a history of recurrent chest infections
over the past 4 years. The patient had been treated intermittently with
several courses of antibiotics. Apart from his chest infections, he had
no significant medical or surgical history. On examination, the only
significant finding was an area of decreased air entry in the right
lower lobe. Laboratory data revealed no abnormality. A chest radiograph
and, subsequently, a CT were requested.
