Occasionally, an overlying mass (pancreas or stomach) may be mistaken for an AAA. An abdominal bruit is nonspecific for an unruptured aneurysm, but the presence of an abdominal bruit or the lateral propagation of the aortic pulse wave can offer subtle clues and may be more frequently found than a pulsatile mass. Bruits may also indicate the presence of renal or visceral artery stenosis; a thrill is possible with aortocaval fistulae. Patients with popliteal artery aneurysms frequently have AAAs (25-50% of cases).
