title: Bridging bronchus: a rare airway anomaly.
abstract: The authors describe an infant whose right-lower-lobe bronchus arose from the left main bronchus and bridged the lower mediastinum. Other major congenital anomalies were present as well. Possible explanations for crossed airways, which would seem to contradict the current theory of embryonic lung development, are suggested.
