A giant intradiaphragmatic bronchogenic cyst: case report and literature review.

Bronchogenic cysts are congenital lesions developing during early embryogenesis. The intradiaphragmatic location is extremely rare. We present a giant bronchogenic cyst arising from the left crus of diaphragm. Based on our literature review results, intradiaphragmatic bronchogenic cysts have the following characteristics: 1) they are more common in female patients; 2) the patients are usually asymptomatic, or present with symptoms of chest pain, abdominal pain, and hiccups; 3) the cysts located in the left diaphragm are more than those in the right diaphragm, most of which are located in the area of the left diaphragm crus.
