Intradiaphragmatic bronchogenic cyst: report of a rare new case.

Bronchogenic cysts (BCs) are congenital abnormalities commonly found within the mediastinum. Diaphragmatic location is extremely rare. We present a woman in her 60s with an asymptomatic intradiaphragmatic BC. The patient underwent complete surgical resection with primary closure of the left hemidiaphragm. BCs should remain a differential diagnosis of any soft-tissue mass in the region of the diaphragm. Complete surgical resection is recommended even in asymptomatic patients to avoid complications such as infection, rupture, bleeding or malignant transformation.
