A bronchogenic cyst in the middle mediastinum was removed by thoracoscopic surgery. The patient was a 42 year old female whose routine chest roentgenogram showed a huge mass in the middle mediastinum. A CT scan showed a low-density, cystic and lobulated lesion in the chest. MRI revealed that the mass had high signal intensity on both T1-and T2-weighted images. Thoracoscopic surgery was performed under general anesthesia with unilateral ventilation. The thoracoscope was inserted through the 6th intercostal space in the posterior axillary line. The contents of the cystic mass were aspirated. Cytological examination showed no cancer cells. The parietal pleura was divided by a hook, coagulation was performed with electric cautery, and the mass was freed from the mediastinal tissue and pulled out through the chest wall at the 4th intercostal space. The histological diagnosis was bronchogenic cyst. The chest tube was removed on the 2nd post operative day, and the patient was discharged 7 days after surgery.
