摘要
本文综述了各种良性颅内囊肿的组织学、电镜和免疫组织化学特征。包括蛛网膜囊肿、内胚层囊肿、外胚层囊肿和第三脑室的胶质囊肿。在这些良性先天性肿瘤中,列举了一些值得注意的形态学发现。在室管膜下巨细胞星形细胞瘤中观察到局灶性坏死、内皮细胞增殖和α - b -晶体蛋白的免疫反应性。在脑膜血管瘤病中检查阿尔茨海默氏症神经原纤维缠结的精细结构。胚胎发育异常神经外胚层肿瘤的概述,最近认识到新的实体与难治性癫痫发作的年轻患者提供。
[Benign intracranial cysts and certain congenital neoplasms].
Highlights of histological, electron microscopic and immunohistochemical features of various benign intracranial cysts are reviewed. These include arachnoid, endodermal, ectodermal and colloid cysts of the third ventricle. Certain noteworthy morphological findings are enumerated in these benign congenital neoplasms. Focal necroses and endothelial proliferation and immunoreactivity for alpha B-crystallin in some of the giant cells are observed in subependymal giant cell astrocytomas. The fine structure of Alzheimer's neurofibrillary tangles is examined in meningoangiomatosis. An overview of dysembryoplastic neuroectodermal tumor a recently recognized new entity associated with intractable seizures in young patients is provided.
