Answer

Computed tomography (CT) scanning and ultrasonography may be indicated for the evaluation of liver disease for cirrhosis, cholecystitis with hemorrhage, pancreatitis with pseudocyst and hemorrhage, aortoenteric fistula, and other unusual causes of upper gastrointestinal (GI) hemorrhage (UGIB). [2] The 2010 American College of Radiology (ACR) criteria state that CT scanning is particularly useful for localizing obscure UGIB and for evaluating a patient with UGIB and a history of aortic reconstruction or pancreaticobiliary procedure. [37]

CT scanning is useful in the diagnosis of aortoenteric fistula because images may reveal thickened bowel, perigraft fluid collection, extraluminal gas, or inflammatory changes in the area of the duodenum and the aortic graft.
