Magnetic resonance imaging (MRI), performed for accurate characterisation, showed a 4 cm x 4.5 cm cystic lesion, with heterogeneous signal intensity on T2-weighted images, located in the posterior wall of the stomach [Figure 1a]. Finally, the whole greater curvature was mobilised, the cyst and the stomach wall was transected using linear endoscopic stapler (Echelon Flex  60mm; Ethicon Endo-Surgery, Cincinnati, OH, USA) [Figure 1b]. Histopathological examination demonstrated a benign cystic lesion covered by respiratory epithelium transitioning focally into gastric mucosa with inflammation and microfoci of haemorrhages and intact smooth muscle layer, suggesting duplication cysts [Figure 1c].
