Between 1984 and 1992, patients with bronchogenic cysts were treated in our institution: 17 males and 12 females ranging in age from 3 years to 50 years (average 23.4). Two of them were brothers. The majority of the bronchogenic cysts (19 of 29) 65,5% were intraparenchymally located, remaining (10 of 29) 34,5% were located in the mediastinum. Lesions of seven asymptomatic patients were discovered on chest x-ray. Chest pain was the most common respiratory symptoms in twenty-two patients. All patients underwent surgery. Intraparenchymal lesions were removed by segmentectomy or lobectomy. On the other hand a cyst located in the fissure was simply excised. Among the cysts adhering to the trachea, 2 of them required suturation of the trachea due to airway communication. One case developed empyema as a postoperative complication and it was surgically drained. Thirteen operated patients were followed up at an average of 6 months. No sequelae was noted and all patients had normal control chest film.
