Positive 18F-fluolodeoxyglucose (18F-FDG) uptake of adrenal gland on positron emission tomography/computed tomography (PET/CT) was frequently observed in routine workup of both adrenal lesions and other malignant tumors in PET/CT. Positive uptake of adrenal lesions does not necessarily mean malignancy. The purpose of this exhibit is: 1: To show various adrenal diseases showing positive uptake of 18F-FDG. 2: To compare images of positive 18F-FDG PET/CT with other image findings including CT, MRI and other scintigraphy. 3: knowledge of positive uptake of various adrenal lesions may help the diagnosis of both benign and malignant adrenal lesions.  

1. Positive 18F-FDG uptake of malignant lesions adrenal carcinoma malignant pheochromacytoma malignant lymphoma metastasis 2. Positive 18F-FDG upatake of benign lesions adrenal cortical adenoma benign pheochromocytoma adrenal hemorrhage Inflammatory lesions 3. Pitfalls
