A 92-year-old woman presented to our emergency department on April 17, 2008, with a 3-day history of aggravated dyspnea. No aspiration or choking history was noted. Her medical history was notable for hypertension and paroxysmal atrial fibrillation. Non-Hodgkin lymphoma had been diagnosed in 2003, and complete remission was achieved after chemotherapy. She was a nonsmoker, but her primary care physician suspected COPD because of occasional dyspnea with expiratory wheezing.
