Gastric Duplication Cyst in an Adult

Gastric duplication cyst which is a rare anomaly can also be observed in adulthood. Abdominal pain is the most common complaint in adults and most cases are discovered incidentally by radiological examination or gastric endoscopy. Preoperative diagnosis of gastric duplication is difficult and definitive diagnosis requires findings on laparatomy together with histopathological examination of the lesion. Gastric duplication cyst is primarily managed by complete excision. Gastric duplication cyst was suspected on gastric endoscopy and magnetic resonance imaging (MRI) of the abdomen in a 52-year-old woman presented with abdominal pain. She was treated by complete excision of the cyst and the diagnosis was confirmed with the operative findings and histopathological examination of the removed specimen.
