Abstract

Mycotic aneurysm is a rare and life-threatening disorder. Computed tomography (CT) is considered to be the best diagnostic imaging modality that can detect an abdominal aortic aneurysm and changes in the surrounding structures. More recently, F-18 fluorodeoxyglucose (FDG) PET would seem to hold promise for the diagnosis of focal infection and during the follow-up after antibiotic treatment. We present a case of an infected abdominal aortic aneurysm due to Salmonella enteritidis. In this case, a combination of CT and FDG PET/CT provided accurate information for the diagnosis of the infected abdominal aortic aneurysm. Moreover, FDG PET/CT made an important contribution for monitoring response to antibiotic therapy.
