Case Discussion

Gastric duplication cysts are a rare disease representing 2-7% of all gastrointestinal duplications. It is diagnosed early by its symptomatic presentation with nausea, vomiting, weight loss or epigastric mass. The most frequent location is the jejunum-ileum (68%), followed by the colon (18%). Gastric and duodenal duplications represent <7%. In most cases, the treatment is surgical due to the symptoms and the risk of malignant transformation.
