Del Castello syndrome--an unusual presentation.

Del Castello syndrome in a 28-year-old female, characterised by bilateral galactorrhoea, amenorrhoea and hyperinvoluted uterus, has been described. She had hyperprolactinaemia without any demonstrable pituitary tumour. She was successfully treated with two short courses of bromocriptine and was spontaneously cured after her second conception. The case is discussed with a brief review of the literature.
