Se describe un caso de hipofisítis granulomatosa en una mujer de 28 años, con síntomas de cefalea y diplopia ocasionada por una parálisis del nervio MOE del ojo izquierdo. Paradójicamente no presentaba alteraciones hormonales.
Los estudios radiológicos y la TAC no mostraban alteraciones patológicas. Solamente la Resonancia Magnética demostró un aumento de tamaño del contenido selar, que hacía sospechar un adenoma de hipófisis.
Fue operada y tratada con corticoides, mejorando progresivamente de sus molestias.
El estudio hitopatológico confirmó la existencia de una inflamación granulomatosa crónica e inespecífica en la hipófisis.
We report a case of granulomatous hypophysitis in a 38 year old woman who suffered cephalea and dyplopia, caused by left abducens palsy. No relevant endocrine alteration was observed.
Plain x-ray films and C.T. were normal, but M.R.I. disclosed an enlarged sellar content, what was supossed to be a pituitary tumor.
Transphenoidal surgical exploration of the sella revealed a hypertrophic hypophysis, without adenomatous tissue.
Histopathological analysis of the taken samples showed definite signs of granulomatous hypophysitis.
After two months of corticoid treatment, dyplopia disappeared.
