Abdominal aortic aneurysm with initial symptom of duodenal obstruction

Duodenal obstruction as the initial symptom of an abdominal aortic aneurysm is unusual. We report the 13th case and our findings from a review of the literature. This entity should be considered in an older individual when duodenal obstruction is associated with findings of a pulsatile abdominal mass, or when abdominal films show calcification of the aneurysm or bone erosion.
