Abstract

Gastric Duplication cysts form a very small subset of the rare Duplication anomalies involving the gastrointestinal tract. They have variable presentation and may present as an upper abdominal mass with obstructive or pressure symptoms. Excision of the lesion followed by histopathology clinches the diagnosis. We describe the case of an infant with gastric duplication cyst involving the greater curvature of the stomach with features of gastric outlet obstruction. He had upper abdominal distension with repeated episodes of non-bilious vomiting for one month. On examination, two conspicuous swellings with visible peristalsis from left to right side were found. Ultrasound and computed tomogram scan of the abdomen confirmed the diagnosis of cystic lesions in relation to the greater curvature of the stomach, suggesting a diagnosis of Gastric Duplication Cyst. There were no other associated anomalies in this patient. Excision of the lesion led to resolution of symptoms and histopathology confirmed the diagnosis.
