[A case of Swyer-James syndrome with bilateral lesions]

A 16-year-old female was admitted for the treatment of bronchial asthma. She had a history of measles pneumonia at four years of age. Her chest radiograph revealed right unilateral hyperlucency. She was diagnosed as having Swyer-James syndrome from the results of computed tomography, pulmonary angiography, bronchoscopy, and perfusion-ventilation scintigrams, which revealed unsuspected bilateral involvement, and irregularity of severity and distribution. In addition, she had a hypoplastic right upper bronchus, pulmonary hypertension, pneumothorax, and bronchial asthma. The findings of bilateral involvement, irregular distribution, and bronchial lesions strongly suggest that the etiology in this case was damage to the airways caused by measles infection in childhood.
