Unilateral pulmonary artery hypoplasia is a rare anomaly. Chest radiograph shows diminished hilar vessels and hyperlucency of a uniIateral lung. We present a 78-year-old man with dyspnea on effort, who was followed as a patient with left pulmonary artery hypoplasia and pulmonary hypertension. Follow-up chest radiograph and CT incidentally showed a nodule in the left upper lobe, which was diagnosed as adenocarcinoma through transbronchial biopsy. Although the partial pressure of oxygen in arterial blood was 56.5 Torr, he was considered appropriate for surgery because a lung perfusion scintigram showed extremely poor perfusion in the affected lung. Video-assisted thoracic surgery (VATS) lobectomy was safely performed. After the operation, both his symptom and the partial pressure of oxygen in arterial blood were markedly improved, with the latter increasing to 71.9 Torr.
