[Two cases of miliary tuberculosis with SIADH].
Two cases of miliary tuberculosis with syndrome of inappropriate secretion of antidiuretic hormone (SIADH) were reported. Case 1. A 70-year-old woman suffering from general fatigue and appetite loss developed neck stiffness and stupor three days after admission. The chest X-ray film showed a miliary pattern in both lungs. The lumber puncture showed high pressure and increased leucocytes in the cerebrospinal fluid. Serum natrium concentration was 113 mEq/L. Tubercle bacilli were seen in the broncho-alveolar lavage fluid by the Ziehl-Nielsen staining. An improvement in electrolytes balance was produced by 2.5% NaCl and antituberculous treatment, then her mental function recovered. Case 2. A 71-year-old man was admitted with gastric ulcer. When he developed dry cough thirty days after admission, the chest X-ray film showed a miliary pattern in both lungs. Acute respiratory failure advanced concomitantly. Tubercle bacilli were seen in the sputum (Gaffky 5) by the Ziehl-Nielsen staining. Antituberculous treatment was started. Although the miliary shadow improved gradually, hyponatremia was rather progressing. The following values for serum constituents were determined: sodium, 118 mEq/L; antidiuretic hormone, 10.3 pg/ml. Antituberculous treatment and supplement of NaCl (10 g/day) improved serum natrium level. He had no mental disturbance in his clinical course. In both cases, thyroid, renal and adrenal function were normal. Systemic edema and dehydration did not exist at the state of hyponatremia, and it was very clear that laboratory data were compatible with SIADH criteria. Miliary tuberculosis is one of the least commonly recognized causes of SIADH.
