Abstract:
Accurate characterization of adrenal lesions in lung cancer is essential in the staging of the disease. Computed tomography and magnetic resonance imaging as well as fluorodeoxyglucose-positron emission tomography (FDG-PET) imaging are used to differentiate adrenal metastases from benign adenomas. Although FDG-PET is highly accurate in this regard, benign adrenal cortical adenomas have been shown to accumulate FDG, although to a lesser degree. We present a patient with a history of lung cancer and FDG accumulation in a benign adenoma, probably reflecting areas of chronic inflammation also seen within the gland at pathology.
