Surgical Management of Concurrent Partial Anomalous Pulmonary Venous Return and Lung Cancer of the Same Lobe.

Partial anomalous pulmonary venous return (PAPVR) is a rare congenital left-to-right shunt where pulmonary veins drain into systemic circulation. This is a presentation of the case of a patient with concurrent PAPVR and adenocarcinoma of the same lobe. The pulmonary veins of right upper lobe drained into superior vena cava (SVC), whereas the middle and lower lobes veins drained into the left atrium as two distinct vessels. Surgeons should always perform a diligent search for anomalous vascular structure using computed tomographic (CT) angiography prior to surgery. In our case, surgical approach was "safe" because both pathologies developed in the same lobe.
