title: Occurrence of pituitary adenoma in craniofacial fibrous dysplasia: a neuroendocrine and neuroradiological case study.
abstract: An 18 year old man with fibrous dysplasia of bone and several endocrine abnormalities was investigated. Laboratory tests showed high levels of prolactin, TSH and GH and low levels of testosterone and LH. TRH and GnRH showed normal responsiveness of the pituitary in spite of the high hormonal levels. The circadian rhythms disclosed no abnormalities of hypothalamic control. The neuroradiological study revealed pathological tissue but no positive sign of a pituitary adenoma, although the sella turcica polytomograms did suggest erosion of the floor. Our data are compatible with the presence of a mixed adenoma or adenomas of the pituitary. We emphasize the importance of a correct study, including neuroradiological and neuroendocrine investigations, in patients with fibrous dysplasia of bone.
