Presentation of GIST as jejuno-jejunal intussusception

Gastrointestinal stromal tumours (GISTs) are rare tumour. It comprises 0.2% of gastrointestinal tumours and only 0.04% of small intestinal tumours. Usually this tumour is found in people in their 60s. These tumours can be found anywhere in the gastrointestinal tract but most commonly found in the stomach (40-60%). Patients with GISTs usually have vague and nonspecific symptoms. We present a 17year-old with complain of abdominal pain, distension, and few episodes of vomiting. All laboratory investigations were normal. The ultrasonography (USG) and computed tomography (CT) were suggestive of jejuno-jejunal intussusception. The patient had emergency exploratory laparotomy with resection of the segment with five cm healthy margin, and end to end anastomosis. Patient was discharged after 4 days and remains well. This case report highlights the rarity of GISTs in the concern of age (17 year old), site (Jejunum) as well as presentation (intussusception).
