Abstract

Bowel ischemia following embolization is the major complication of arterial embolization in gastrointestinal bleeding. Although mild ischemia recovers with conservative treatment, perforation should be treated surgically. We report a case of gastrointestinal stromal tumor mistaken for an abscess following embolization of superior mesenteric artery. A 72-year-old female was referred to the emergency room complaining of hematochezia and hematemesis. Endoscopic examination revealed a tiny mucosal defect with spurting bleeding at distal duodenum. Hemostasis could be achieved by embolization of superior mesenteric artery. After ten days, abdominal CT scan showed an abscess-like feature around distal duodenum, but the small bowel series did not show leakage of contrast. Endoscopy revealed round intestinal wall defect. She underwent laparotomy owing to the possibility of perforation and abscess, but surgical findings showed 5 cm mass based on the jejunum just caudal to ligament of Treitz. The mass was finally diagnosed as gastrointestinal stromal tumor combined with necrosis.
