Abstract：
METHODS: We present the case of a 59-year-old man who had MIS L4-5 decompression. He presented the next day with intractable back and leg pain. Magnetic resonance imaging revealed ventral displacement of the cauda equina and a subdural collection on the right L3/L4 nerve roots. Revision decompression revealed occult durotomy caudal and contralateral to the index decompression.
CONCLUSIONS: Minimally invasive spine (MIS) surgery leverages shorter operative time and reduced postoperative pain. Yet, decreased exposure can make identification and management complications challenging. This report highlights occult durotomy and spinal subdural extra-arachnoid hygroma in patients with postoperative nerve compression after seemingly uncomplicated MISS.

摘要：
方法：我们介绍了一个59岁的男性MISL4-5减压的病例。第二天，他出现了棘手的背部和腿部疼痛。磁共振成像显示马尾神经的腹侧移位和右L3/L4神经根上的硬膜下集合。翻修减压术显示出隐匿性的尾部和对侧减压术。
结论：微创脊柱（MIS）手术可缩短手术时间并减轻术后疼痛。然而，减少暴露会使识别和管理并发症具有挑战性。本报告重点介绍了看似简单的MISS术后神经受压患者的隐匿性硬膜切开术和脊髓硬膜下蛛网膜外水瘤。
