Spinal extradural arachnoid cysts are one of the rare causes of symptomatic spinal cord compression. Among them, occurrence of multiple cysts at the same spinal segment is rarely described in the literature. They appear to be extradural outpouchings of arachnoid that communicate with the intraspinal sub-arachnoid space through a small defect in the dura, filled by cerebrospinal fluid. Pathogenesis of these lesions is still unclear. Surgical excision is considered as the gold standard treatment. We present a 7-year-old female child who presented with spastic paraparesis. Her magnetic resonance imaging showed a thoracic posterior extradural arachnoid cyst, whereas, intraoperatively we found multiple cysts, which were excised completely. Neurological symptoms gradually recovered after surgical decompression.
脊髓硬膜外蛛网膜囊肿是导致症状性脊髓压迫的罕见原因之一。其中，同一脊髓节段出现多个囊肿的情况在文献中鲜有描述。它们似乎是蛛网膜的硬膜外袋状膨出，通过硬脑膜上的一个小缺损与椎管内蛛网膜下腔相通，腔内充满脑脊液。这些病变的发病机制仍不清楚。手术切除被认为是金标准治疗方法。我们报告一名7岁女童，她表现为痉挛性截瘫。其磁共振成像显示为胸段硬膜外蛛网膜囊肿，然而，术中我们发现了多个囊肿，并将其完全切除。手术减压后神经症状逐渐恢复。
