This is a report of a case of gastric duplication discovered in a 42-year-old woman by ultrasound examination. A clearly bounded cubic cyst was found along the lesser curvature of the stomach under the left lobe of the liver close to the lasser curvature by ultasound examination and computed tomographic scanning. An upper GI series and endoscopic examination disclosed a protrusion in the lesser curvature near the cardia. There was no communication between the gastric lumen and the extragastic mass. However, surgery confirmed continuation between the mass and the lesser curvature of the stomach. The mass was resected with the involved portion of the gastric wall. The resected mass was a cyst 4 cm in diameter totally filled with fluid similar to pus. Histopathological studies revealed the strata of the mucous membrane, muscular layer and serous membrane. The mucous membrane showed a pseudostratified columnar epithelium containing goblet cells. Part of the muscular layer communicated with the muscular layer of the gastric wall, but not with the gastric lumen. We must keep this unusual case in mind when we detect peritoneal cyst by ultrasound and/or CT examination.
