A 62 year old man with 4 days of cough
For example, a 30-year-old woman with shortness of breath and fever (maybe a virus: pneumonia, of course) for 3 months (tuberculosis, multiple pulmonary emboli, lupus, sarcoidosis) recently returned from India (malaria, hepatic abscess, weird tropical disease) where she was visiting her mother, who was dying of breast cancer (anxiety; metastases from breast, ovarian, or colonic cancer; maybe she visited a guru and got toxic herbal medications), and so on.

Summary StatementIn summary, we have a 62 year old man with remote tobacco use, previous pneumonia and coronary disease who presents with 4 days of productive cough and increasing dyspnea. He has not had fever or hemoptysis and there has been no travel, sick contacts, weight change, chest pain, calf tenderness, orthopnea or nocturnal dyspnea. On exam, he is tachypneic with labored breathing, tachycardic with a normal BP and T: 37.7. Sinuses are not tender and there is no cervical adenopathy. Lungs are notable for dullness in the right, anterior lower lung zone with diminished breath sounds, crackles, egophony and tactile fremitus. He has a leukocytosis and chest radiograph shows an infiltrate in the right middle lobe.
