Question 19
A 60-year-old man has had a cough without production of much sputum for the past week. On physical examination he is afebrile. There are decreased breath sounds at the right lung base. A chest radiograph reveals an area of consolidation in the right lower lobe. He is given antibiotic therapy, but a month later the radiographic picture has not changed, and his cough continues. A bronchoalveolar lavage is performed and yields atypical cells along with scattered alveolar macrophages. Which of the following is the most likely diagnosis?
A Mycoplasma pneumonia
B Bronchioloalveolar carcinoma
C Sarcoidosis
D Pulmonary infarction
E Silicosis
