We report the case of a 53-year-old man with a chronic periaortitis (CP) in whom Fluorine-18-Fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT) has been useful in assessing the disease extent at diagnosis, in evaluating the treatment response, in diagnosing the relapse, and in monitoring the disease activity during follow-up (Fig. 1). This case highlights the usefulness of FDG-PET/CT at different times in patients with CP.Fig. 1

A 53-year-old man was admitted to our hospital for a suspected chronic periaortitis (CP) based on clinical (abdominal pain), laboratory data (increased serological inflammatory markers, such as erythrocyte sedimentation rate [ESR] and C reactive protein [CRP]), and imaging data (an abdominal periaortic tissue with a longitudinal extent of 7 cm was detected at CT). The patient did not perform a contrast enhanced CT scan for renal insufficiency. The patient underwent a FDG-PET/CT to assess the metabolic activity of the periaortic ti ...
