While it can occur anywhere in the gastrointestinal tract, gastroduodenal intussusception resulting from gastrointestinal stromal tumors (GIST) is a rare clinical finding.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Case presentation<\/jats:title>\n                    <jats:p>Here we report a case of gastroduodenal intussusception caused by gastric GIST in a 68-year-old female. She sought medical attention for symptoms including nausea, recurrent vomiting of blood, and epigastric pain. Plain computed tomography (CT) scan revealed a well-defined mass located on the gastric fundus, which was confirmed intraoperatively. Endoscopy demonstrated that the mass had prolapsed into the duodenum. Based on these findings, gastroduodenal intussusception secondary to a gastric tumor was diagnosed. The patient underwent successful partial gastric resection, which confirmed a mass originating from the gastric fundus and prolapsing into the duodenum. The postoperative pathological diagnosis was low-risk gastric GIST according to the National Institutes of Health (NIH) criteria. The patient was followed up for 12 months, undergoing CT imaging at 6 months and both CT and gastroscopy at 12 months, with no evidence of tumor recurrence.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Gastric GISTs are a rare but clinically significant cause of adult gastroduodenal intussusception, typically necessitating surgical intervention. Multimodal imaging, particularly CT, plays a crucial role in preoperative diagnosis, while histopathological examination remains essential for definitive diagnosis and risk stratification. Treatment should be individualized based on tumor size, location, and patient factors.<\/jats:p>\n
