CTICasesPartial Anomalous Pulmonary Venous Return and Aortic Pseudo-Coarctation

Imaging findings
Contrast-enhanced computed tomography and magnetic resonance angiography of a 15-year-old patient demonstrate a partial anomalous pulmonary venous return where an anomalous right upper pulmonary vein drains directly into the superior vena cava. There is also a mild narrowing and kinking of the distal aortic arch consistent with a pseudo-coarctation of the aorta, without a significant pressure gradient.
Key takeaways
PAPVR and pseudo-coarctation of the aorta are congenital cardiovascular anomalies that can co-occur. While PAPVR represents a left-to-right shunt that may lead to right-sided volume overload, pseudo-coarctation is typically a benign anatomical variant (kinking of the aorta) that does not produce a significant hemodynamic obstruction or require surgical intervention, unlike true aortic coarctation.
