INTRODUCTION: A small bowel gastrointestinal stromal tumor (GIST) is a rare neoplasm of the gastrointestinal tract. The manifestation of bleeding is a diagnostic challenge and could present as a life-threatening situation that needs urgent intervention.
PRESENTATION OF CASE: 64-year-old woman consulted for episodes of melena and anemia. The upper and lower endoscopies were not diagnostic. Capsule endoscopy (CE) revealed a probable jejunal hemangioma, however double-balloon enteroscopy and magnetic resonance imaging (MRI) did not show any intestinal nodule but MRI show a pelvic mass apparently related to the uterus confirmed by a gynecologist. Even so, the patient returned with melena, and a contrast-enhanced computed tomography (CT) scan again identified a pelvic mass, highlighting that its vascularization drained into the superior mesenteric territory and seemed to invade the jejunum, with active bleeding, suspicious for jejunal GIST. A laparotomy was performed to remove the jejunal mass. Histopathology and immunohistochemical studies confirmed the diagnosis.
DISCUSSION: Bleeding is a common symptom in small bowel GISTs but its diagnoses could be difficult because its location. In most cases, gastroscopy and colonoscopy are not useful and CE or imaging studies are necessary to find the cause of bleeding. Moreover, it has recently proved that bleeding is a prognostic risk factor because it is related to tumor rupture and tumor invasion of blood vessels.
CONCLUSION: In this case, bleeding caused by small bowel GIST was misdiagnosed in endoscopic procedures and the clinical management was delayed. CT angiography was the most effective investigation to detect the source of bleeding.
