Abstract/OtherAbstract:
On one hand pituitary microadenomas with autonomous character and those, which had been influenced by hypothalamic disorders, are summarized and discussed. On the other hand, the neurosurgical management of tumours, adjacent to or involved with the hypothalamus, are described. Endocrinologically active pituitary adenomas are characterized by their hormone excess of ACTH, GH, and prolactin. In Cushing's disease endocrine and clinical remission occurred in 74%. 3 patients out of this group showed a reincrease of ACTH after a period of remission, indicating a possible hypothalamic influence. In acromegaly the hypothalamic influence is also discussed. One patient with an ectopic GRF-producing tumour showing a reincrease of GH levels after successful transsphenoidal adenomectomy has been described. In microprolactinomas, 7 patients out of 45 showed a reincrease of prolactin-levels after a period of normalization, we also discussed hypothalamic disorders. Tumours with suprasellar extension such as macroadenomas without endocrine activity and meningiomas are removed nowadays with minimal risk for the life of the patients. In craniopharyngiomas radical excision is accompanied by a high risk of hypothalamic defects caused by mechanical lesions and possible secondary vasospasm. Finally the excision of a hamartoma growing from the floor of the third ventricle into the interpeduncular cistern is discussed. Up to now the successful excision could be documented by endocrinological data, which give no sign of further growth of the hamartoma.
