Hormonelle Befunde bei Kindern mit zentraler Manifestation einer Neurofibromatose Recklinghausen

Abstract Hormone parameters were evaluated in 14 children with cerebral manifestation of N.R. to find a possible involvement of the hypothalamo-pituitary axis. In addition to growth hormone and prolactin stimulation, tests of gonadotropic, thyreotropic and adrenocorticotropic function were performed. 6 patients had insufficient growth hormone secretory capacity, and 6 times an increased prolactin-stimulation was found; in one patient ACTH-reserve was diminished. A brain tumour was found in 5 of these 8 patients with impaired hormone results; however, in 3 cases pathologic results were found only after operation.
