Abstract
Disseminated cryptococcosis most commonly occurs in immunosuppressed patients and can rarely affect the adrenal glands. We report on a patient with biopsy proven bilateral adrenal cryptococcosis resulting in primary adrenal insufficiency, which was evaluated with whole-body positron emission tomography/computed tomography scan using (18)F-FDG. Both enlarged adrenal glands presented intensely increased (18)F-FDG activity in the periphery, while central necrotic regions were photopenic. Although diagnosis was established by adrenal gland biopsy, (18)F-FDG positron emission tomography/computed tomography scan can significantly contribute to the assessment of disease activity and monitoring of treatment response. Furthermore, fungal infections should always be considered when encountering hypermetabolic adrenal masses, especially in the setting of immunodeficient patients.
