[Hyponatremia and myxedamatous coma].
The authors report a case of coma due to peripheral myxoedema with severe hyponatremia (111 mq) and low urinary sodium. The clinical and metabolic disorders regressed within ten days under treatment with thyroid. The frequency of hyponatremia during myxoedema coma is recalled and the pathogenic mechanism discussed. Although the adrenal origin seems excluded, there is possibly some hypervasopresinism, but it seems finally that the thyroxin-dependent hyponatremia is of renal origin.
