CTICasesWandering Pulmonary Vein with Tracheobronchus
Imaging findings
CT shows a congenital tracheal bronchus arising from the right lateral wall of the trachea above the carina, supplying the right apical segment. The venous drainage of this segment is supplied by a wandering pulmonary vein forming an venous arcade to the left atrium.
Key takeaways
Wandering pulmonary veins and tracheal bronchi are congenital developmental variants. They frequently coexist in the same lobe, representing a localized abnormality in embryogenesis of both the airway and pulmonary vasculature.
