A gastric duplication cyst is not a common anomaly of the alimentary tract. The most common site of alimentary tract duplication is the ileum. We found a non-communicating gastric duplication cyst, along with the greater curvature of the stomach during feeding gastrostomy for isolated Oesophageal atresia. We are reporting a gastric duplication cyst associated with isolated Oesophageal atresia and left side one additional floating rib. This is the third case report of gastric duplication cyst with Oesophageal atresia in English literature.
