AbstractPartial anomalous pulmonary venous return (PAPVR) is an uncommon congenital abnormality that occurs in 0.4 to 0.7% of postmortem examinations. Ninety percent of these anomalies are associated with an atrial septal defect. Partial anomalous pulmonary venous return occurs more commonly on the right than the left and is manifested by abnormal return of the pulmonary veins to the central venous circulation. Most patients are asymptomatic, but when symptoms are present they are due to shunting of oxygenated blood to the venous circulation. We submit the case of a recently activated solider who presented with dyspnea on exertion refractory to inhaled corticosteroids and an 8.5-mm solitary pulmonary nodule. Further diagnostic imaging revealed PAPVR. Our case appears to be the first report of a solitary pulmonary nodule as the initial presentation of a right upper lobe PAPVR with return to the superior vena cava in the absence of associated atrial septal defect.
