Gastrointestinal stromal tumor (GIST) is the most common mesenchymal tumor of the gastrointestinal tract and may occasionally present with acute gastrointestinal bleed (GIB). Multidetector computed tomography (MDCT) angiography is extremely useful in demonstrating the tumor as well as the presence of active hemorrhage, thereby guiding subsequent interventional or surgical management. We report a case of a 38-year-old man who presented with acute-onset melena and compensated shock, whose source of bleed remained elusive on endoscopy. MDCT angiography performed on a dual-energy scanner showed a jejunal tumor with active intraluminal contrast extravasation. The tumor was subsequently resected and the patient did well on follow-up. This was one of the few instances when MDCT angiography demonstrated active bleeding in a GIST and the first such case demonstrated on a dual-energy scanner.
