Extradural arachnoid cyst in the spine is an uncommon cause of spinal cord compression in the paediatric population. Most reported cysts have communication with the intrathecal subarachnoid space through a small defect in the dura. The reported child had spinal cord compression caused by a large spinal extradural arachnoid cyst in dorsal spine that did not communicate with the intradural subarachnoid space. Surgical excision of cyst was done with recovery of neurological deficit postoperatively.
脊柱硬膜外蛛网膜囊肿是小儿脊髓受压的罕见原因。大多数报道的囊肿通过硬脑膜上的小缺损与鞘内蛛网膜下腔相通。报道的这名患儿因胸椎巨大硬膜外蛛网膜囊肿导致脊髓受压，该囊肿与硬膜内蛛网膜下腔不相通。对囊肿进行了手术切除，术后神经功能缺损得到恢复。
