A 62-year-old female presented with multiple sacral nerve root cysts manifesting as localized unilateral perineal pain. Myelography just after contrast material injection revealed multiple cysts at the sacral level. However, perioperative dye injection showed hardly any flow in the reverse direction. Only the S3 nerve was constricted by hyperplasia of the dura mater, and adhered to the cyst wall. Other nerves were not constricted, nor adhered to cyst walls. The S3 nerve constriction and tight adhesion was the cause of the pain. The one-way flow of spinal fluid from the spinal subarachnoid space to the cysts is probably closely correlated with cyst formation.
一名62岁女性因多个骶神经根囊肿就诊，表现为局部单侧会阴疼痛。注入造影剂后立即进行的脊髓造影显示骶段有多个囊肿。然而，围手术期染料注射显示几乎没有反向流动。仅S3神经被硬脑膜增生压迫，并与囊肿壁粘连。其他神经未受压迫，也未与囊肿壁粘连。S3神经受压和紧密粘连是疼痛的原因。脑脊液从脊髓蛛网膜下腔单向流入囊肿可能与囊肿形成密切相关。
