title: [Tumors in the region of the sella turcica].
abstract: Tumors of the pituitary gland can lead to limitation of hypophysis function (hypophysis insufficiency) or hypersecretion of different hormones (acromegaly, Cushing's syndrome, prolactinoma, TSH-secreting adenoma). The optic chiasma lies in close proximity to the pituitary gland and can be compressed by tumors leading to visual disturbances (bilateral hemianopsia). Tumors can be separated into hormone secreting and hormone inactive tumors, as well as into microadenoma with a diameter <10 mm and macroadenomas >10 mm. A rare group of tumors of the hypophysis region are craniopharyngiomas, meningiomas, germinomas, gliomas, metastases and granulomotous inflammations, such as sarcoidosis and tuberculosis.
