Six days later, 18F-fluorodeoxyglucose positron emission tomography-CT confirmed three growing inflammatory aneurysms, on the left common femoral (diameter 64x72 mm, Standardised Uptake Value (SUV) 12) and left (diameter 43x29 mm, SUV 10) and right (diameter 35x28 mm, SUV 10) popliteal arteries (Figure 2); the abdominal aorta was normal.
