case_images: Chest computed tomography (CT) (Figure 1) incidentally detected a 6-cm mass in the left adrenal lodge.
case_images: Abdominal MRI scan: presence of a big heterogeneous adrenal lesion, with hyperintense spots due to hematic content.

case_images: A 18F-fluorodeoxyglucose positron emission tomography (18F-FDG-PET) performed in order to exclude any extra-adrenal uptake: no significant metabolic activity in the adrenal mass but intense uptake in supra- and subdiaphragmatic brown adipose tissue was detected, likely due to noradrenergic-stimulated glucose uptake (Figure 3).
