Gastrointestinal stromal tumors (GISTs) are rare, occurring in 10 - 15 per million, and 0.2% of all gastrointestinaltumors, and is generally considered a solitary tumor. This study presented a 57 year-old female with abdominalpain and intermittent vomiting for 6 months. Acute abdomen series did not show any evidence of a small bowelobstruction. Esophagogastroduodenoscopy (EGD) suggested partial small bowel obstruction. A contrast enhancedCT scan (CECT) of the abdomen demonstrated jejuno-jejunal intussusception induced by an intraluminal tumorand another two mesenteric tumors confirmed by histopathology and immunohistochemistry as GISTs. Thepatient had complete resection for treatment. She recovered without complication and remained well. This studyreported a rare case of multiple primary GISTs with unusual presentation as intussusception. CECT is able to detecttumors, their location, suggest diagnosis, and define complications and metastasis.
