Summary
Adrenal adenomas are observed in up to 7% of the population and are predominantly non-functional, increased 18 F-fluorodeoxyglucose (FDG) uptake is seen in only a small portion of them on 18 F-FDG positron emission tomography/computed tomography (PET/CT) imaging.In this report, we present the sequential 18 F-FDG PET/CT imaging findings of 2 patients with radiologically or pathologically confirmed adrenal adenomas who had severely altered 18 F-FDG uptake patterns in adrenal lesions in different imaging studies of the same patient.In light of these findings, we wanted to highlight that evaluating adrenal adenomas as cross-sectional with semi-quantitative PET/CT parameters obtained from single imaging may cause misinterpretation.
