title: Dyspnea with 'wheezing' in a 75-year-old female.
abstract: This case demonstrates the importance of including upper airway obstruction in the differential diagnosis of 'asthma'. Clues to the diagnosis can be obtained from the physical examination, inspiratory and expiratory flow volume curve studies and radiologic studies. The definitive treatment is determined by the underlying etiology and the extent of the upper airway obstruction.
