The lung parenchyma, which was within the fissure due to poor lobulation between the middle and lower lobes, was safely divided. The artery was carefully dissected from the caudal side after inferior pulmonary vein dissection. Intraoperatively, A7 was observed between the superior and inferior pulmonary veins and in the front of the lower bronchus near the anterior hilum. Right lower lobectomy and mediastinal lymph node dissection were performed. Preoperative three-dimensional computed tomography (CT) angiography revealed an aberrant mediastinal A7 in the right main pulmonary artery. We report the case of a 71-year-old woman with an aberrant mediastinal A7 who underwent right lower lobectomy for lung cancer (cT1bN0M0, stage IA2). A mediastinal mediobasal segmental pulmonary artery (A7) from the right main pulmonary artery is extremely rare.
