Higher surgical risks of open repair for inflammatory abdominal aortic aneurysm (I-AAA) associated with severe adhesion around the aneurysm have been reported. Recently endovascular aneurysm repair (EVAR) for I-AAA has been advocated. We experienced an I-AAA with increased fluorine-18 fluoro-deoxy-glucose (
18F-FDG) uptake in the aneurysm wall, which was revealed by positron emission tomography/computer tomography(PET-CT), and disappeared 6 months after EVAR. The mechanism, by which inflammation of the aneurysm wall was improved, could not be specified, but a reduction of the pressure load on the aneurysm wall by EVAR may have played a role.
