Background: Bronchopulmonary sequestration, simply called as pulmonary sequestration, is a relatively rare congenital anomaly with few reports of initial diagnosis occurring during adulthood. It consists of a nonfunctioning mass of lung tissue that lacks normal communication with the tracheobronchial tree and that receives its arterial blood supply from the systemic circulation. Case Presentation: We report two cases with bronchopulmonary sequestration and a short review of the clinical/radiologic features of bronchopulmonary sequestration. Conclusion: Look carefully at the retrocardiac area of chest radiography in adults for the definition of unexpected lesions. It can be bronchopulmonary sequestrations. It can be diagnosed easily with a feeding artery by an aberrant systemic artery which usually arises from the aorta.
