Bronchogenic cysts above and below the diaphragm: report of eight cases.

Bronchogenic cysts are developmental foregut anomalies usually located within the mediastinum. Although typically asymptomatic, infection or compression of adjacent structures may become prominent. Surgical excision is recommended to establish diagnosis, alleviate symptoms if present, and prevent future complications. We report our recent experience with bronchogenic cysts including 7 located within the mediastinum and a rare instance of a cyst below the diaphragm.
