Abstract Disclosure: I. Vina: None. R. Sánchez: None. I.C. Fernández: None. C. Vázquez: None. Background: Tuberculous adrenalitis is an extremely rare cause of Addison disease in developed countries. Since more than 80% of the primary adrenal insufficiency cases in the developed world are caused by autoimmune disease, tuberculous adrenalitis often go unnoticed. The aim of this case report is to remember that, even if it is not frequent, TB cannot be overlooked as a cause of longstanding primary adrenal insufficiency, even without evidence of pulmonary or extra glandular TB disease. Herein, we reported a case of bilateral tuberculous adrenalitis, wherein the patient initially presented with gastrointestinal symptoms, hyperpigmentation, bilateral adrenal masses, and no evidence of extra-adrenal tuberculosis. Case report: A 57-year-old woman from Madrid with no medical relevant history, was admitted to our hospital with 4 months of evolution of asthenia, weight loss (-8kg) and nausea that in recent days has been accompanied by fever and anorexia. He also refers progressive hyperpigmentation for the past 3 years. Denies recent travel abroad. On physical examination hypotension (80/53 mmHg) and generalized hyperpigmentation predominantly in the oral mucosa stand out. Blood test: Glu: 41 mg/dL, Na+: 122 mmol/L, K+: 4.8 mmol/L, ACTH: 922 pg/mL, Cortisol: 4.63 ug/dL, Anti-Hydroxylase Ab and Anti-Adrenal glands Ab: negative A computed tomography scan of the abdomen with intravenous contrast revealed bilaterally enlarged adrenal glands with small bilateral calcifications (12-18mm). TB QuantiFERON test: positive. She was initially treated with saline serum and intravenous hydrocortisone causing her symptoms to improve significantly in a few days and was subsequently discharged on hydrocortisone and fludrocortisone and proper treatment for TB Adrenalitis and follow-up in outpatient clinics. Conclusions: Although not frequent, infectious causes should always be kept in mind, such as the etiology of adrenal insufficiency in a patient with long-term compatible symptoms, even though it is a developed country, given world globalization, which makes infectious diseases highly transmissible between countries and continents.
