Subcutaneous findings in 18F-FDG PET-CT

Learning Objectives The reader will learn the appearance of numerous hypermetabolic cutaneous lesions that can be incidentally encountered in PET-CTs of oncology patients.

A wide spectrum of benign etiologies are associated with incidentally detected increased subcutaneous FDG uptake in cancer patients. These lesions may pose a diagnostic challenge. The purpose of this exhibit is to illustrate a variety of hypermetabolic subcutaneous lesions in the PET-CT iof oncology patients. Lesions illustrated include hypermetabolism due to therapy, infection, inflammation or recent cosmetic procedures. The cases will expose the reader to the typical appearance of infrequently encountered subcutaneous lesions and give the reader confidence in interpretation
