Abstract

Chronic, intermittent GI bleeding is defined as obscure when routine diagnostic examinations of the GI tract, including barium and endoscopic studies, fail to reveal the cause of bleeding. Our patient had significant bleeding and extensive evaluation including upper endoscopy, small bowel enteroscopy, enteroclysis, colonoscopy, and provocative angiography with urokinase, without the source of bleeding detected. This report describes a noninvasive novel approach using helical CT scanning with water as oral contrast and rapid injection of intravenous iodinated contrast material and thin slices obtained to diagnose the site of recurrent, obscure GI bleeding related to cholesterol crystal embolization to the small intestine.
