Right lung cancer with partial anomalous pulmonary venous return and absent right upper lobe

摘要

When a vascular shunt is present, major lung resection may cause acute right heart failure. We report a case of right lung cancer with ipsilateral partial anomalous pulmonary venous return (PAPVR) and absent right upper lobe managed by pneumonectomy. A 48-year-old former smoker was diagnosed as right lung cancer; chest computed tomography (CT) revealed an anomalous right pulmonary vein draining into inferior vena cava. Bronchus of right upper lobe was not found in fiberoptic bronchoscopy. Right pneumonectomy was performed. Pathological examination revealed a T2aN2M0 squamous lung cancer. The patient tolerated well without notable descending of arterial oxygen pressure.
