History of Present Illness: A 54-year-old man presented to clinic with chronic cough, dyspnea on exertion, unintentional weight loss, and night sweats. Seven months before, he developed dyspnea on exertion and symptoms did not improve with inhalers. Four months prior to presentation, he was treated for presumed community-acquired pneumonia of the right lower lobe. Neither symptoms nor chest radiograph improved with multiple courses of antibiotics. In the four weeks prior to presentation his symptoms progressed to the point that he was unable to walk in his house without significant dyspnea.

Review of systems: 10-pound unintentional weight loss and six weeks of night sweats.

Past Medical History, Social History and Family History: The patient had a 15-pack-year smoking history and quit 15 years prior to presentation. He had no other past medical history, surgical history, family history, nor medications.

Physical Examination: Vital signs were normal on presentation. Physical exam showed faint wheezing and decreased breath sounds over the right posterior lung fields.

Radiography: Chest radiograph demonstrated dense opacification in the superior segment of the right lower lobe (Figure 1).
