概述

脊髓空洞症是一种慢性进行性脊髓变性疾病。空洞多位于颈髓,亦可累及延髓称为延髓空洞症。延髓空洞症可单独出现或与脊髓空洞症并发。典型的临床表现是节段性分离性感觉障碍,病变节段支配区肌萎缩及营养障碍。病因及发病机制(1)先天性发育异常本病常合并扁平颅底、小脑扁桃体下疝、颈肋、弓形足等崎形,故认为脊髓空洞症是脊髓先天性发育异常所致。有人认为由于胚胎期脊髓神经管闭合不全所致。(2)脑脊液动力学异常颈枕区先天异常,第四脑室出口处闭塞,使脑脊液正常循环受阻,结果脉络丛所产生的脑脊液不断冲击脊髓中央管使之逐

The association between syringomyelia and malformative conditions, and in particular the Chiari malformations has been examined in some depth, with a wealth of clinical, radiological, pathological, surgical and experimental studies see, for review [1-6]. Current ideas about syrinx formation centre on alterations in cerebrospinal fluid flow near the craniocervical junction and alterations in vascular and interstitial fluid dynamics, which by a variety of proposed mechanisms are thought to result in an accumulation of fluid within the cord, and subsequent intramedullary cavitation or dilation of the central canal [1,3,7]. In these conceptions, with a few exceptions, [6], syringomyelia is often thought to be a chronic, progressive, and late consequence of the underlying malformation or acquired disease [1,5,8,9]. Syringomyelia in the context of terminal cord myelocystocele, on the other hand, is proposed to be a straightforward ballooning of the terminal ventricle in communication with a patent central canal [10-12].

脊髓空洞症和畸形病症之间的关联,特别是Chiari畸形已经进行了深入研究,有大量的临床,放射学,病理学,外科学和实验研究可供参考[1-6]。关于syrinx形成的当前观点集中在颅颈交界处附近的脑脊液流动的改变以及血管和间质液动力学的改变,这被认为通过各种提出的机制导致脐带内的液体积聚,以及随后的髓内空洞或扩张中央管[1,3,7]。在这些概念中,除了少数例外[6],脊髓空洞症通常被认为是潜在的畸形或后天性疾病的慢性,进行性和晚期后果[1,5,8,9]。另一方面,在终末髓鞘细胞囊肿的情况下,脊髓空洞症被认为是与专利中央管连通的末端心室的直接气球[10-12]
