Two patients each with symptoms of an endobronchial lesion showed decreased unilateral lung perfusion upon radionuclide imaging. Chest films were normal except for hilar lymph node calcifications. Bronchography and tomography revealed compression and obstruction of the bronchial tree by the calcified lymph nodes, accounting for the patients' symptoms. Incomplete bronchial obstruction or collateral air drift accounted for the normal appearance of the lungs on the PA chest films.
两名患有支气管内病变症状的患者在放射性核素成像时显示单侧肺灌注减少。胸部X光片除肺门淋巴结钙化外均正常。支气管造影和体层摄影显示钙化淋巴结对支气管树造成压迫和阻塞，这解释了患者的症状。不完全性支气管阻塞或侧支气流导致后前位胸部X光片上肺部外观正常。
