title: Rapid regression of pituitary tumours during bromocriptine treatment of women with hyperprolactinaemia.
abstract: Four hyperprolactinaemic women with large pituitary adenomas with suprasellar extension were given primary tumour therapy with bromocriptine. The treatment resulted in rapid tumour regression in all the women, as verified by repeated computerized tomography (CT) scans. Pronounced visual field defects were present in three of the four women before treatment. All of them had marked improvement of vision within a few days after the initiation of bromocriptine therapy and they regained normal or nearly normal visual fields during the treatment. The raised serum prolactin concentrations decreased to normal levels in all the women. Thus, medical treatment with bromocriptine can induce rapid tumour regression in patients with hyperprolactinaemia and large pituitary tumours.
