Abstract

¹⁸Fluoro-desoxy-glucose positron-emission tomography (F-FDG-PET) may be useful to diagnose complications of endocarditis in difficult cases. We report the case of a young patient who had endocarditis and a painful leg. FDG PET/computed tomography showed hypermetabolism in the leg, and duplex ultrasound suggested an inflammatory aneurysm at the site of the hypermetabolism. The combination of FDG-PET/computed tomography and duplex ultrasound is useful to diagnose mycotic aneurysm in the setting of bacterial endocarditis.
