题21:e [注解] Simmonds综合征的垂体前叶机能低下症几乎是同义使用。垂体嫌色素性腺瘤是其重要原因之一。肢端肥大症是生长激素过多症,主要由于垂体嗜酸性细胞腺瘤,也有与嫌色素细胞混合的腺癌。 侏儒症的原因有骨病,营养,代谢病及原发性等。所谓垂体性的是由垂体分泌生长激素减少所致,多属特发性(80％)。因颅咽瘤所致者只占侏儒症的5％左右。 尿崩症的原因,特发性及继发性者各半,在继发性中,异位松果体瘤为重要原因之一。 Question 21: e [Note] Anterior pituitary hypopnea syndrome in Simmonds syndrome is almost synonymous. Pituitary pigmentoma is one of the important reasons. Acromegaly is growth hormone hyperactivity disorder, mainly due to pituitary eosinophilic adenoma, but also with suspected pigment cells mixed with adenocarcinoma. The reasons for dwarfism are bone disease, nutrition, metabolic diseases and primary. The so-called pituitary secretion of growth hormone by the pituitary decreased due mostly idiopathic (80%). Due to craniopharyngeal tumor caused only about 5% of dwarfism. Diabetes insipidus causes, idiopathic and secondary half, in secondary, ectopic pineal tumors as one of the important reasons.
