CTICasesAnomalous Pulmonary Venous Drainage
Imaging findings
CT angiography shows a venous variant where an accessory left-sided pulmonary vein joins the right-sided pulmonary veins to form a common ostium before draining into the left atrium.
Key takeaways
Anomalous pulmonary venous drainage patterns can represent benign developmental variants that do not cause significant hemodynamic shunts. High-resolution CT angiography is useful to trace these variants and prevent accidental injury during thoracic surgery.
