We present the case of a 37 year-old female who had disseminated tuberculosis (TB) with bilateral adrenal involvement resulting in primary adrenal failure (Addison's disease) with refractory hyponatraemia and possible extrapontine 'myelinolysis'. Laboratory results were remarkable for adrenal insufficiency. A Mantoux reaction was positive with evidence of pulmonary miliary TB. The magnetic resonance imaging scan showed all the characteristic changes of adrenal TB.
