・下垂体腫瘍を認めた場合には,機能性下垂体神経内分泌腫瘍(PitNET)および下垂体機能低下症の可能性を考慮し,内分泌基礎値を評価する.
・下垂体機能異常(機能性PitNETおよび前葉機能低下症,中枢性尿崩症)は,指定難病の定める要件を満たせば,医療助成対象となる.
・副腎皮質刺激ホルモン(ACTH)依存性クッシング症候群の鑑別診断には,血管内カテーテルを用いた下錐体静脈洞サンプリングが有用である.
Pituitary tumors can cause an excess or deficiency of anterior pituitary hormones. Functional pituitary neuroendocrine tumors(PitNETs)include growth hormone(GH)-producing tumors, adrenocorticotropic hormone(ACTH)-producing tumors, thyroid-stimulating hormone(TSH)-producing tumors, and prolactin(PRL)-producing tumors. Comprehensive preoperative endocrine evaluation is essential for appropriate therapeutic decision-making and safe surgery.
Here, we focus on the diagnosis and evaluation of PitNETs using endocrine function tests and intravascular catheterization for inferior petrosal sinus sampling for pituitary tumors.
