Secretion of hypothalamic and pituitary hormones by non-endocrine tumours.
That non-endocrine cancers can produce clinical syndromes of apparent hormone excess has been known for some time (Rees and Ratcliffe, 1974). Now there is ample clinical and biocheinical evidence that many polypeptide hormones may be produced and released by human tumours which originate in tissues which are not normally regarded as sites for the physiological production of the hormones. In som...
متن کاملPituitary tumours: pituitary incidentalomas.
Clinically non-functioning pituitary adenomas range from being completely asymptomatic, and therefore being detected either at autopsy or as incidental findings on head magnetic resonance imaging (MRI) or computed tomography (CT) scans performed for other reasons (often referred to as 'pituitary incidentalomas'), to causing significant hypothalamic/pituitary dysfunction and visual field comprom...
متن کاملHypothalamic and pituitary injury.
The hypothalamic-pituitary axis is recognized to an increasing extent as a physiological unit which influences and is influenced by endocrine and autonomic function. Anatomically, however, a clear distinction is to be drawn, with regard to both cellular and vascular anatomy, betweenthe neural (hypothalamus and neurohypophysis) and the glandular epithelial (pars distalis) components of the axis....
متن کاملPituitary and hypothalamic physiology.
Professor P. M. Daniel has described in the first paper the nervous pathways connecting the hypothalamus to the posterior pituitary and how the posterior pituitary merely stores the hormones vasopressin, oxytocin (which has no clearly defined function in man), and neurophysin, the large molecule or molecules which bind the other hormones. For many years the anterior pituitary was thought to be ...
متن کاملNon-adenomatous pituitary tumours.
Apart from pituitary adenomas, a number of tumours may arise from within the sella presenting a diagnostic and therapeutic challenge at a multidisciplinary specialist level. This article focus on the most commonly diagnosed non-adenomatous pituitary tumours (craniopharyngiomas, Rathke's cleft cysts and meningiomas) and provides data on their pathogenesis, diagnosis and treatment.
