High (18)F-Fluorodeoxyglucose Uptake in Adrenal Angiomyolipoma: Case Report and Review of Literature

Adrenal angiomyolipoma is an extremely rare tumor, although computed tomography (CT) or magnetic resonance imaging findings of adrenal angiomyolipoma have been reported, there are no reports regarding integrated fluorine-18-fluorodeoxyglucose positron emission tomography and computed tomography ((18)F-FDG PET/CT) imaging. We report a case of adrenal angiomyolipoma showing a significantly high uptake of (18)F-fluorodeoxyglucose on PET/CT study. The maximal standardized uptake value (SUV) of the lesion was 18.8. Adrenal angiomyolipoma can show an intense uptake in FDG-PET/CT, and this can easily be confused with a malignant disease. Adrenal angiomyolipoma should be considered as one of the differential diagnoses in cases of adrenal incidentaloma with intense FDG uptake.
