A 64-year-old man was referred to A&E by his general practitioner with worsening back and acute bilateral leg pain and weakness with urinary retention. His MRI scan demonstrated spinal canal stenosis at the level of L1-L2 and a diagnosis of cauda equina syndrome (CES) was made. CES is a rare neurological condition caused by compression of the central spinal nerves at the termination of the cord. CES is a surgical emergency requiring urgent assessment and treatment. The patient underwent urgent surgical decompression; however, he required a second surgery for further decompression as repeat MRI showed persistent stenosis with further extension. Intraoperative Doppler ultrasonography revealed an intradural lesion, which was surgically excised and found to be a sequestrated lumbar disc in the intrathecal space. The patient showed significant neurological improvement post revision decompression.
一位 64 岁男性因背部疼痛加重和急性双侧腿部疼痛、无力伴尿潴留，被全科医生转诊至急症室。他的磁共振成像扫描显示 L1-L2 水平椎管狭窄，并诊断为马尾综合征 (CES)。CES 是一种罕见的神经系统疾病，由脊髓末端中央脊神经受压引起。CES 是一种需要紧急评估和治疗的手术急症。患者接受了紧急手术减压；然而，由于重复 MRI 显示持续狭窄并进一步加重，他需要进行第二次手术以进一步减压。术中多普勒超声显示硬脊膜内病变，手术切除后发现为椎管内的游离腰椎间盘。经修正减压后，患者的神经功能显著改善。
