TOE excluded infective endocarditis but revealed 2 small outpouchings, measuring 2.5 x 2.4 cm and 0.45 x 0.6 cm, in the ascending aorta, which were also seen on CT chest (Figure 1(a)). PET scan using 18F-fluorodeoxyglucose (FDG) tracer showed moderate FDG uptake in the aortic outpouchings and the diagnosis of mycotic pseudoaneurysm was made (Figure 1(b)).
