CTICasesMeandering pulmonary vein
Imaging findings
Contrast-enhanced chest CT shows an anomalous pulmonary vein arising from the left upper lobe, coursing into the mediastinum near the expected left superior pulmonary vein ostium (which is absent), then turning and running inferiorly to drain into the left inferior pulmonary vein.
Key takeaways
A meandering pulmonary vein is a rare vascular anomaly characterized by an anomalous course of a pulmonary vein within the lung parenchyma before draining into the left atrium (often via another pulmonary vein). It is frequently associated with congenital stenosis or developmental absence of the normal venous ostium.
