A 46‐year‐old woman was referred to the emergency department with severe epigastric pain. Physical examination, electrocardiogram, chest X‐ray, and laboratory findings were normal. A contrast‐enhanced computed tomography (CT) (Figure 1) was performed. The scan showed an invagination of the stomach wall. The diagnosis of an organo‐axial gastrogastric intussusception was made, probably caused by a well‐described round mass of 3 cm. This lesion showed a deep ulceration with an air‐fluid level (Figure 1).

The patient underwent gastric endoscopy and biopsy. An ulcerated submucosal mass at the gastric fundus (Figure 2) was seen. Echo‐endoscopy (Figure 2) showed a single sharply delineated submucosal hypo‐echoic mass. The biopsy confirmed the diagnosis of a benign gastrointestinal stromal tumor (GIST). A laparoscopic partial gastrectomy was performed.

Intussusception or invagination of the proximal gastrointestinal tract is uncommon, and only few gastrogastric intussusceptions have been reported. Most intussusceptions have been reported in children, where 90% of cases are idiopathic. In adults however, in up to 90% of cases an underlying pathology could be found. Neoplasms account for 65% of all causative lesions in adults.1 Gastrointestinal stromal tumors (GIST) have been found anywhere along the gastrointestinal tract but are more frequent in the stomach, accounting for 60% of cases.2
