Contrast-enhanced computed tomography (CT) revealed a cystic mass behind the stomach, and considering the visible thick walls of the cyst in CT the possibility of foregut duplication cyst was put forward; however, the cyst was confined to the posterior wall of thestomach and there was no extension to thethorax (Figure 1a-c).
