A 42 year-old female was admitted to our hospital for further examination of left unilateral hyperlucency on chest X-ray. She was diagnosed as Swyer-James syndrome by bronchography, pulmonary arteriography, pulmonary perfusion scan and ventilation scan. Bronchial arteriography and mesurements of PO<sub>2</sub> in pulmonary arteries demonstrated no evidence of bronchial arteries-pumonary arteries shunt. After administration of sublingual nifedipine, there was a marked decrease in pulmonary artery resistance and a moderate decrease in PaO<sub>2</sub>. It was considered that the vessels of the affected side could be dilated by this drug. Aerosol inhalation scintigraphy revealed that mucociliary transport mechanism was not impaired in the central respiratory tract of the affected side.
