FDG positron emission tomography/computed tomography in the detection of aortic endograft infection

Focal increased tracer uptake was seen on the PET image [Figure 1]a and b, which localized to the wall of the descending thoracic aorta at the site of the stent graft on the fusion images [Figure 1]c and d. The corresponding CT image [Figure 1]e and f however, merely showed non-specific wall thickening. {Figure 1} In recent years there has been a steady increase in the number of endovascular aortic aneurysm repairs (EVAR), attributable to reduced perioperative complications vis-a-vis open surgical grafting.
