Indium-111-labeled leukocyte scanning has been shown to be a highly sensitive and specific imaging modality in the detection of abscess formation. Leukocyte infiltration occurs in a variety of inflammatory states as well as some noninflammatory states, leading to false-positive results. We report a case of an inflammatory abdominal aortic aneurysm imaged by 111In. It is not clear whether the activity noted is due to the inflammatory nature of the aneurysm or to hemorrhage present within the wall of the aneurysm.
