Platypnea-orthodeoxia is encountered in a variety of cardiac, pulmonary, and hepatic disorders. We report its occurrence in a 59-year-old man who had had combined external-beam and high dose-rate iridium brachytherapy for a stage I non-small-cell carcinoma of the right upper lobe 2 years earlier. The post-radiation course was complicated by a severe radiation bronchitis; the onset of platypnea-orthodeoxia signalled the development of severe bronchial stenosis that was transiently relieved, initially by dilatation, and later by stent placement, though the patient ultimately died of a pulmonary hemorrhage. The dosage of brachytherapy given, the combined external-beam therapy, and the long survival after completion of radiation therapy were likely factors in the development of bronchial stenosis. We discuss the tomographic and bronchoscopic features of radiation-induced bronchial stenosis.
