Gastric endophytic gastrointestinal stromal tumor (GIST) as a rare cause of gastroduodenal intussusception: case report and literature review

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.
