Addison’s Disease due to Bilateral Adrenal Tuberculosis on 18F-Fluorodeoxyglucose Positron Emission Tomography Computed Tomography

Abstract

We present a case of a 60-year-old woman diagnosed with disseminated tuberculosis with bilateral adrenalitis resulting in Addison’s disease. The 18-fluorodeoxyglucose (18-FDG) positron emission tomography computed tomography (CT) was performed, which revealed increased FDG uptake in the neck, mediastinal, and abdominal lymph nodes, and both adrenal glands, similar to the lesions noted on CT. We suspected the patient to have a lymphoma; therefore, axillary biopsy was performed, which revealed chronic granulomatous lesion with focal caseous necrosis.
