A 59-year-old woman was pointed out abnormal shadows on chest film and has been followed up since 2001. In October 2006, she consulted our hospital for further examination. Computed tomography (CT) showed double cystic lesions located in the right lower lobe, and in the paraesophageal region. The patient underwent video-assisted thoracic surgery (VATS) right lower lobectomy and resection of the tumor in the mediastinum. The content of the tumor were greenish and whitish discharge. Histopathologically, both were bronchogenic cysts. The patient was discharged on 17th postoperative day and doing well for 6 months postoperatively.
