Thoracoscopic resections of bronchogenic cysts arising in the posterior mediastinum: a report on 3 patients.

We report 3 cases of patients with bronchogenic cyst arising in the posterior mediastinum. The patients were a 19-year-old male, a 36-year-old female and a 33-year-old female, whose cysts were detected as abnormal shadows in the chest. In 2 of them, neurogenic tumors were suspected preoperatively. We performed thoracoscopic resection for the 3 tumors. Bronchogenic cysts may occur ectopically, and the posterior mediastinum must be sufficiently recognized as a rare but possible ectopic site.
