Key result
Sequential short-interval FDG PET/CT identifies benign hypermetabolic lipomatous tumors by tracking disappearing hypermetabolism.
Why the study?
Intense FDG activity in lipomatous tumors can mimic malignant neoplasms, leading to potential false-positive interpretations.
Can short-interval sequential FDG PET/CT studies help define the benignity of hypermetabolic lipomatous tumors in oncological patients?

Can short-interval sequential FDG PET/CT studies help define the benignity of hypermetabolic lipomatous tumors in oncological patients?
Short-interval sequential FDG PET/CT can help differentiate benign hypermetabolic lipomatous tumors from malignant neoplasms, potentially avoiding unnecessary major surgery.
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.

Hod et al. (2023) conducted a case report in Hypermetabolic Lipomatous Tumor (n=1). Sequential short-interval FDG PET/CT studies was evaluated on Defining the benign nature of the tumor. Sequential short-interval FDG PET/CT studies helped define the benign nature of a hypermetabolic lipomatous tumor by demonstrating gradually disappearing hypermetabolism.
