Abstract: Tuberculous effusion is one of the rare causes of hyponatremia. Although other mechanisms have been described, Syndrome of Inappropriate secretion of ADH(SIADH) is usually the most common among them. We report a case of 75-year-old who had two admissions in view of altered sensorium before diagnosing tuberculous effusion causing SIADH. This report emphasizes on the uncommon presentation of a fairly common disease.
