The Usefulness of Short-Interval Sequential FDG PET/CT Studies in Defining the Benignity of Hypermetabolic Lipomatous Tumor

We present an interesting case of incidentally detected lipomatous tumor in an oncological patient that could result in a false-positive interpretation by exhibiting intense FDG activity similar to that of a malignant neoplasm. Careful evaluation of FDG uptake changes on sequential short-interval PET/CT studies was helpful in defining the benign nature of the tumor as the hypermetabolism was gradually disappearing obviating the need for a major surgery.
