We report on a rare case of thoracoscopic surgery for a patient with an aberrant pulmonary artery of the inferior lobar branch (A7) in the right lower lobe. A 69-year-old woman presented with a chief complaint of an abnormal shadow on chest radiography. Computed tomography (CT) revealed a 14-mm solid nodule in the right lower lobe. The patient was diagnosed with lung cancer by bronchoscopic biopsy, and a surgery was planned. Preoperative thin-slice CT and three-dimensional CT showed an aberrant A7 branching from the right main pulmonary artery. The right lower lobe and lymph node dissection was performed safely under a video view. Preoperative evaluation of this anomaly is important for a safe surgery.
