Se presentan dos casos clínicos de apoplejía hipofisaria tras anestesia espinal, ambos con cefalea y una parálisis del III par craneal. Uno de ellos con alteración visual adicional e hiponatremia. Se revisa la bibliografía en busca de las claves para un diagnóstico precoz y se propone la hipotensión arterial como mecanismo patogénico de la apoplejía.
Two cases of pituitary apoplexy occurring after spinal anaesthesia are described. Both presented with headache and III par palsy, one of them with additional visual disturbance and hyponatremia. A bibliographical review has been done, looking for early diagnostic keys. We propose the arterial hypotension as a possible pathogenetic mechanism of pituitary adenoma apoplexy.
