Abstract
Gastrointestinal bleeding of obscure origin (GIB-OO) is defined as clinically manifest gastrointestinal bleeding that persists or recurs without identification of the cause after a complete upper and lower gastrointestinal endoscopy (UGIE and colonoscopy). It often poses a diagnostic and therapeutic challenge for the clinic that needs a good coordination between gastroenterologists, inter- ventional radiologists and surgeons. We present a case of OGIB- OO secondary to a gastrointestinal stromal tumor (GIST) that bears out the importance of including CT angiography in the diagnosis of a GIB-OO.
