A gastric GIST which causes gastroduodenal intussusception is rare. A Pubmed search only identified 21 published cases of gastroduodenal intussusception due to gastric GIST. Only 2 of them mentioned ultrasound without further analysis. Here, we report a case of gastroduodenal intussusception due to a gastric GIST with multiple imaging especially ultrasound. A 72-year-old Chinese woman was admitted to hospital because of epigastric pain, black stool lasting and occasional vomiting for 2 months. She underwent abdominal ultrasound, endoscopy, and contrast enhanced CT in turn. Abdominal ultrasound revealed a hypoechoic, medium-sized lesion beside pancreatic head. Endoscopy showed a submucosal lesion of gastric fundus overlapping into duodenum. The lesion manifested slight enhancement in the arterial phase on enhanced CT scans. The patient underwent laparoscopic exploration and partial gastrectomy. The histological examination revealed a low-risk gastric GIST of spindle-shaped cell type.
