FDG PET-CT Findings in Epiploic Appendagitis

Positron emission tomography (PET) using flourodeoxyglucose (FDG) is routinely used for initial staging and restaging of colorectal cancers. However FDG PET studies can suffer from false-positive tracer uptake due to a variety of physiological and inflammatory conditions arising in the abdomen and pelvis. Epiploic appendagitis is one such condition that can give rise to increased glucose concentration on a FDG PET study. We describe the etiology, clinical presentation, computerized tomography scan and FDG PET-computed tomography findings of this unusual inflammatory condition in an operated case of colorectal cancer.
