(A) Computed tomography (CT) angiogram of the abdomen and pelvis (sagittal view) demonstrating abdominal aortic graft peri-luminal soft tissue density thickening with slight stranding, and a small focus of gas centrally. (B) Axial view of the CT angiogram. (C) Magnetic resonance imaging (MRI) showing a chain of abscesses within the right gluteal region, in particular, the interface between the right gluteus medius and maximus. There is intense associated inflammatory oedema and enhancement. (D) Axial view of the MRI.

CT abdomen and pelvis revealed soft tissue thickening and stranding around the aortic graft, with locules of gas seen within the vessel (Fig. 1A and B). Pelvic magnetic resonance imaging (MRI) showed a chain of abscesses within the right gluteal region (Fig. 1C and D).

(A) Computed tomography (CT) angiogram of the abdomen (axial view) showing the abdominal aortic aneurysm with a maximum diameter of 54 mm. (B) CT angiogram of the abdomen (axial view) demonstrating a 58 mm diameter abdominal aortic aneurysm following a five month interval. (C) Fluorodeoxyglucose (FDG) positron emission tomography (PET) CT showing abnormal FDG uptake within the aneurysmal wall. Note: Moderately prominent radiotracer uptake in the left ventricular myocardium probably represents physiological tracer uptake related to the dietary preparation for the study and is not thought to represent endocarditis. (D) Axial view of the FDG PET CT.

CT angiogram revealed a 58 mm AAA (Fig. 2A and B). AAA repair. A pre-operative FDG PET CT was performed, now revealing multiple foci of FDG avidity with the aneurysmal wall, suspicious of an active inflammatory or infective process (Fig. 2C and D).
