A unique case of unilateral pulmonary edema from partial anomalous pulmonary venous return in conjunction with superior vena cava stenosis

Abstract While PAPVR is most commonly an incidental finding on chest CT, a unique case is presented where PAPVR in conjunction with SVC stenosis resulted in chronic symptomatic asymmetric pulmonary edema. The case reflects an unusual anatomic cause of unilateral edema, as a combination of both congenital and subsequently acquired anatomic anomalies.
