We report a 14\u2010month\u2010old girl presenting with failure to thrive, recurrent emesis, hematemesis, and severe duodenitis with ulceration. Laboratory evaluation revealed marked hypergastrinemia (1781\u2009pg\/mL), and initial imaging was unrevealing. Persistent symptoms prompted repeat imaging, which identified a 3.7\u2009\u00d7\u20095.2\u2009cm gastric duplication cyst causing gastric outlet obstruction. Surgical resection confirmed gastric mucosa within the cyst, and postoperative gastrin levels normalized. This case represents one of very few reports linking gastric duplication cysts to hypergastrinemia, likely due to isolation of functional gastric mucosa within a closed lumen, resulting in excessive gastrin secretion and peptic injury. The case underscores the importance of considering duplication cysts in pediatric patients with poor growth and the utility of repeat imaging when symptoms persist despite negative initial studies.<\/jats:p>","DOI":"10.1002\/jpr3.70176","type":"journal-article","created":{"date-parts":[[2026,4,6]],"date-time":"2026-04-06T10:04:48Z","timestamp":1775469888000},"page":"428-431","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Gastric duplication cyst causing hypergastrinemia in an infant"],"prefix":"10.1002","volume":"7","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4777-4794","authenticated-orcid":false,"given":"Nathan","family":"Bryan","sequence":"first","affiliation":[{"name":"Division of Gastroenterology Children's National Hospital Washington DC USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ian","family":"Leibowitz","sequence":"additional","affiliation":[{"name":"Division of Gastroenterology Children's National Hospital Washington DC USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,4,6]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.1148\/radiographics.13.5.8210590"},{"key":"e_1_2_7_3_1","doi-asserted-by":"publisher","DOI":"10.1007\/s13244-018-0660-z"},{"key":"e_1_2_7_4_1","doi-asserted-by":"publisher","DOI":"10.1097\/MPG.0b013e31829b6914"},{"key":"e_1_2_7_5_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00261-021-03239-w"},{"key":"e_1_2_7_6_1","doi-asserted-by":"publisher","DOI":"10.1007\/s10396-014-0548-6"},{"issue":"2","key":"e_1_2_7_7_1","article-title":"Intra\u2010abdominal cysts not originating from liver, spleen, or kidney in children: assessment of the diagnostic value of ultrasound features","volume":"34","author":"Alamdaran SA","year":"2024","journal-title":"Iran J Ped"},{"key":"e_1_2_7_8_1","doi-asserted-by":"publisher","DOI":"10.1002\/j.1536-4801.1998.tb00755.x"},{"key":"e_1_2_7_9_1","doi-asserted-by":"publisher","DOI":"10.5223\/pghn.2019.22.2.189"},{"key":"e_1_2_7_10_1","doi-asserted-by":"publisher","DOI":"10.1186\/s40792-016-0203-0"}],"container-title":["JPGN Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/jpr3.70176","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/full-xml\/10.1002\/jpr3.70176","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/jpr3.70176","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,8,13]],"date-time":"2026-08-13T14:59:17Z","timestamp":1786633157000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1002\/jpr3.70176"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,4,6]]},"references-count":9,"journal-issue":{"issue":"3","published-print":{"date-parts":[[2026,8]]}},"alternative-id":["10.1002\/jpr3.70176"],"URL":"https:\/\/doi.org\/10.1002\/jpr3.70176","archive":["Portico"],"relation":{},"ISSN":["2691-171X","2691-171X"],"issn-type":[{"value":"2691-171X","type":"print"},{"value":"2691-171X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026,4,6]]},"assertion":[{"value":"2025-08-24","order":0,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2026-03-14","order":2,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}},{"value":"2026-04-06","order":3,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}]}}
