Abstract

Abstract : Abstract: We present a case of a type Ia endoleak detected using 18 F-FDG PET/CT 10 years after an abdominal aortoiliac endovascular aneurysm repair in an 83-year-old man. The 18 F-FDG PET/CT scan was performed to evaluate a solitary pulmonary nodule but, in addition, demonstrated unexpected blood pool activity outside the stent graft and within the abdominal aortic aneurysm sac, indicating an endoleak; no FDG activity should be present within the aneurysm sac after stent graft placement. A subsequent CT angiogram confirmed the endoleak. This case illustrates the value of PET/CT in unexpectedly demonstrating this serious, late complication of endovascular aneurysm repair.
