Asymptomatic bronchogenic cyst of the mediastinum

Bronchogenic cysts of the mediastinum are benign anomalies of the ventral foregut. The majority of adult patients are asymptomatic. Chest roentgenograms and computed tomographic scans are the primary diagnostic tools. Other procedures may be required, depending on the presentation and the entities being considered. Thoracotomy and complete resection are the recommended treatment. The patient described here represents a typical case of asymptomatic bronchogenic cyst detected on routine roentgenography.
