分泌激素的垂体瘤系腺垂体内的独立结节,直径小于10mm者,称为微腺瘤(mi-croadenoma),常规尸检中,垂体微腺瘤的发生率约为2.7～22.5％。正常组织与微腺瘤之间常有明显界限,许可有选择性地切除腺瘤,而保留剩余垂体的功能。较大肿瘤可压迫邻近的正常腺体,扩展至蝶鞍外,侵犯视交叉和邻近组织,侵袭性肿瘤腐蚀骨骼,海绵窦,蝶窦或脑。本文描述垂体腺瘤(包括微腺瘤)的分泌,放射和治疗的进展。 内分泌学 放免测定各种垂体前叶激素,可以评价库兴氏综合征,肢端肥大症或泌乳分泌瘤等病人的垂体分泌功能。甲状腺激素基础水平可测量甲状腺的功能,通过促甲状腺释放激素的反应,可以测量垂体促甲状腺的储备能
Hormone secretion of the pituitary gland pituitary gland independent nodules, diameter less than 10mm, known as micro-adenoma (mi-croadenoma), routine autopsy, pituitary microadenoma incidence of about 2.7 to 22.5%. There are often clear boundaries between normal tissue and microadenomas, allowing selective excision of adenomas while preserving the function of the remaining pituitary gland. Larger tumors can compress nearby normal glands, extend to the sella, violate the optic chiasm and adjacent tissues, and aggressive tumors erode bones, cavernous sinus, sphenoid sinus or brain. This article describes the progress of the secretion, radiation and treatment of pituitary adenomas, including microadenomas. Endocrine radioimmunoassay to determine a variety of anterior pituitary hormone, you can evaluate the Cushing’s syndrome, acromegaly or lactation secretion of patients such as pituitary secretion. Thyroid hormone can measure the basic level of thyroid function, by thyroid-releasing hormone response, pituitary thyroid can be measured reserve energy
