Hiponatremia grave como manifestación inicial de síndrome de Sheehan de diagnóstico tardío: caso clínico / Hyponatremia secondary to panhypopituirarism: report of one case

ABSTRACT

Hyponatremia is common among older people and its possible causes are not thoroughly investigated in this age group. We report a 69 years old female with a history of hypothyroidism in treatment that consulted for malaise, anorexia and a severe hyponatremia that required hospital admission. A new interrogation, revealed that the patient suffered an uterine hemorrhage in 1977, remaining with agalactia. She also referred asthenia since 1990. Her serum cortisol was below normal limits and a sella turcica magnetic resonance imaging revealed a pituitary atrophy. The patient was treated with cortisol and discharged in good conditions.
