The bronchopulmonary sequestration is a region of lung parenchyma that has an incomplete or no connection with the airways and is supplied by an aberrant artery arising from the aorta or one of its branches. The anatomy of supplied artery is very important during operation. We present a case of pulmonary sequestration supplied with left gastric artery. The patient was 61 years old male and had hemoptysis. The left lower lung was cystic bronchiectasis and a few air-fluid level on chest CT. Also, in aortogram, arterial supply was from left gastric artery of abdominal aorta branches. Left lower lobectomy and abnormal arterial ligation was done.
