title: Severe exertional dyspnea in a patient with localized emphysema.
abstract: The case of a middle-aged, male smoker who presented with progressive severe dyspnea is described. The cause of the progressive severe dyspnea remained unexplained after a comprehensive history, physical examination, chest radiograph, electrocardiogram and spirometry. Subsequent investigations resulted in a diagnosis of localized pulmonary emphysema. Detailed exercise testing helped uncover the physiological basis of the patient's extreme dyspnea.
