A previous CT had raised suspicion of a space-occupying lesion in the left hypochondrium in a context of aspecific constitutional symptoms and inflammatory parameters. The diagnosis of panniculitis was confirmed at laparoscopic biopsy directed by the PET findings. Follow-up 18F-FDG PET/CT after 1 month of corticosteroid therapy showed complete disappearance of the abdominal hypermetabolic foci. Copyright © 2018 Wolters Kluwer Health, Inc. All rights reserved.
