A case of mobile tumor of the cauda equina was presented with a brief review of factors relating to the mobility. A 66-year-old man was admitted to our hospital complaining of left lumbago aggravated by coughing or assuming the supine position. However, neurological examination failed to reveal any abnormalities. The initial myelography showed complete obstruction above the superior border of the L1 vertebra, while the second myelography showed the same obstruction, but it had moved upwards to the superior border of T12. Surgery revealed an elastic, soft tumor and cystic dilatation of the subarachnoid space above and below the tumor. The tumor was mobile but originated from a single elongated and tortuous nerve of the cauda equina. Pathologic examination revealed neurinoma.
本文报告一例马尾神经鞘瘤病例，并简要回顾了与肿瘤活动度相关的因素。一名66岁男性因咳嗽或仰卧位时左腰痛加重入院。然而，神经系统检查未发现任何异常。初次脊髓造影显示L1椎体上缘水平完全梗阻，而第二次脊髓造影显示相同部位梗阻，但已上移至T12椎体上缘。手术发现一个质地柔软且有弹性的肿瘤，肿瘤上下蛛网膜下腔呈囊性扩张。肿瘤可活动，但起源于一条单一的、细长且迂曲的马尾神经。病理检查显示为神经鞘瘤。
