title: Hypothalamic disease presenting as amenorrhoea: value of computed tomography.
abstract: Five women presenting with amenorrhoea (three with secondary amenorrhoea and galactorrhoea, and two with primary amenorrhoea) were shown to have suprasellar abnormalities by computed tomography. Organic hypothalamic disease was confirmed at surgery (craniopharyngioma in three, intra- and suprasellar Rathke's cleft cyst in one, aqueductal stenosis and suprasellar arachnoid cyst in one). Moderate hyperprolactinaemia was present in the first four, while the last had isolated gonadotrophin deficiency of hypothalamic origin. One of the hyperprolactinaemic women had entirely normal residual pituitary function, visual fields and tomography of the sella. Two of the patients with secondary amenorrhoea and galactorrhoea had resumption of menses during bromocriptine therapy before operation. Spontaneous menarche and subsequent pregnancy occurred after ventriculoatrial shunt in the girl with aqueductal stenosis. Organic hypothalamic diseases may present with amenorrhoea (sometimes as the only symptom) more commonly than previously appreciated. Computed tomography should replace conventional tomography of the sella and should be an essential part of the clinical investigation in all patients with amenorrhoea of hypothalamo-pituitary origin.
