Pituitary Tumors

Most pituitary tumors are adenomas. Symptoms include headaches and endocrine; Endocrinopathies arise when the tumor produces hormones or destroyed hormone-producing tissue. The diagnosis is made by an MRI. Treatment includes correction of any endocrinopathy and surgical procedures, radiation therapy and dopamine agonists.

Most tumors of the pituitary and suprasellar region are pituitary adenomas. Pituitary tumors are rare cancers. Meningioma, craniopharyngioma, metastases and dermoid cysts can also develop in the region of the sella turcica.

Most tumors of the pituitary and suprasellar region are pituitary adenomas. Pituitary tumors are rare cancers. Meningioma, craniopharyngioma, metastases and dermoid cysts can also develop in the region of the sella turcica. The adenomas may be endocrine disruptors or hormoninaktiv. Endocrine adenomas produce pituitary hormones; the diameter of many endocrine adenomas is <10 mm (microadenomas). Endocrine adenomas can be divided using histological staining characteristics (eg. As acidophilic, basophilic, chromophobe [non-staining]). The hormones produced often correlate with these characteristics; z. B. acidophilic adenomas lead to an overproduction of growth hormone, basophilic adenomas in an overproduction of ACTH. The most commonly produced hormone prolactin. Each tumor that grows beyond the pituitary gland, can compress the webs of the optic nerve, incl. The optic chiasm. Tumors can also compress tissue of the pituitary gland or hypothalamus or destroy and affect hormone production or secretion. Symptoms and complaints headache may be a result of an enlarging pituitary adenoma, even when the intracranial pressure is not increased. Visual disturbances such as bitemporal hemianopia, unilateral optic atrophy and contralateral hemianopia may develop if the tumor optic nerves compressed (higher visual pathways -. Lesion sites and corresponding visual field defects). Many patients have a endocrinopathy due to hormone deficiency or excess of hormone on: Diabetes insipidus with reduced secretion of vasopressin because of a compression of the hypothalamic amenorrhea and galactorrhea in women and, less frequently, erectile dysfunction, and gynecomastia in men with overproduction of prolactin gigantism before puberty or acromegaly after puberty in growth hormone overproduction of Cushing's syndrome in overproduction of ACTH rarely causes bleeding in a pituitary tumor Hypophyseninsult a sudden headache, visual loss, and ophthalmoplegia. Diagnostic MRI with 1-mm layer management pituitary tumors are suspected in patients with unexplained headaches, blurred vision or characteristic endocrinopathies. It is performed neuroradiological imaging with 1 mm thin layer of lead. MRI is usually considerably more sensitive than CT, v. a. at microadenomas.
