Abstract
Addison's disease is an endocrine disorder characterized by primary adrenal insufficiency due to various causes. Mycobacterium tuberculosis infection was a major cause in the past but is rare nowadays. We describe a patient admitted to our hospital who was diagnosed with tuberculous Addison's disease. LEARNING POINTS: Tuberculosis is a rare cause of Addison's disease in developed countries and so diagnosis is a clinical challenge and requires a high index of suspicion.Tuberculosis should always be considered as a cause of Addison's disease since treating active tuberculosis with steroids alone may have serious consequences.Computed tomography findings can be very helpful in the diagnosis of tuberculous Addison's disease.
