ABSTRACT:Gastrointestinal stromal tumours are relatively common tumours of gastrointestinal tract, most commonly found in the stomach. GISTs are generally asymptomatic but may present with epigastric pain, bleeding and features of gastric outlet obstruction. Adult intussusception is rare and the diagnosis can be delayed because it occurs infrequently, and its symptoms are long standing, intermittent, and nonspecific. Here we present a rare case of gastroduodenal intussusception with gastric stromal tumour as a lead point. Preoperative diagnosis was made on abdominal CT and confirmed by laparotomy and histopathology.
