摘要
本文从病理及发病机制方面分述了脊髓积水症与脊髓空洞症的本质区别,并从现代影像学的改变方面提出了诊断的不同点。指出脊髓积水症多与环枕畸形台并存在,第四脑室正中孔扩大是发生中央管扩张的主要原因。采用环枕区的减压术、中央管与脑室分流或与蛛网膜下腔分流,可使脊髓积水症的病情缓解或停止发展。
The basic differences between hydromyelia and syringa-Myelia were described in this paper according to pathological and patho-genetic mechanism.The diagnosis were also compared depending on neuroi-maging changes. The report showed that mostly hydromyelia was accompanied by atlanto-occipitalis malfarmation and the enlargement of the median hole of the forth ventricle was the main cause of the enlargement of median, cancal The disease could be alleviated through atlanto-occipitalis decom-oression and median cancal subarachnoid shunt operation.
