GASTRIC DUPLICATION CYST: AN UNCOMMON CAUSE OF PAIN ABDOMEN IN AN ADULT

Duplication cysts are rare congenital developmental anamolies of the gastrointestinal tract, the etiology of which is not completely understood. Multiple theories have been proposed to explain their existence including partial twinning, in utero ischemic events, and abnormal endoderm and notochord separation. Complications including infection, intussusception, and perforation can occur. Rarely, these duplications cysts may undergo neoplastic changes. In this report, we present the case of a 40-year-old male with a gastric duplication cyst who presented with vague postprandial dull-aching epigastric pain. Gastric duplication cyst was diagnosed with upper GI endoscopy and CT scan. The cyst was removed by simple excision and patient has remained symptom-free on follow up.
