Bronchogenic cyst of the interatrial septum

Abstract

Bronchogenic cyst is considered as an uncommon congenital anomaly. It can be mostly found in mediastinum or lung. Intracardiac bronchogenic cyst is very rare. We found 2 cases in more than 20000 cardiac surgical cases in our department. The 2 cases bronchogenic cyst arose from interatrial septum (IAS), the preoperative diagnosis were myxoma, but the histological diagnosis were bronchogenic cyst in both cases. Although it is very rare, it should be considered while intracardiac tumor is diagnosed. It is recommended to complete resection of any bronchogenic cyst for primarily diagnostic and potentially therapeutic reasons, and every effort should be made to prevent complications due to injury to nearby tissues. © 2013 Jiang et al.; licensee BioMed Central Ltd.
