Neurilemomas of the cauda equina can present with a clinical syndrome indistinguishable from an acute prolapsed lumbar intervertebral disk. There is backache and sciatica, occasionally after trauma, and straight leg raising is usually limited with signs of L-5 or S-1 root compression. The only distinguishing clinical characteristic is that the pain is worse on recumbency and relieved by sitting or walking. There may be no plain x-ray changes for many years and the tumor is usually at the level of L-2 or L-3 vertebral body. Seven such cases are described in this report.
马尾神经鞘瘤可表现出与急性腰椎间盘突出症难以区分的临床综合征。有背痛和坐骨神经痛，偶尔在创伤后出现，直腿抬高通常受限，并伴有L-5或S-1神经根受压的体征。唯一可区分的临床特征是，卧位时疼痛加剧，坐位或行走时缓解。多年来平片可能无变化，肿瘤通常位于L-2或L-3椎体水平。本报告描述了7例此类病例。
