A spinal extradural arachnoid cyst (SEAC) is a rare condition which can lead to back pain, radiculopathy, and compressive myelopathy. It accounts for approximately 1% of spinal tumours. The exact aetiology of SEACs is not well understood; however, this study is supportive of a traumatic aetiology of this disease in addition to supporting a uni-directional valve as a mechanism of CSF accumulation. The purpose of this study is to review the presentation, work-up, treatment and postoperative course of a patient with SEAC. We present the case of a 40-year-old male with a history of trauma who developed a SEAC and was treated surgically at our unit. Although a rare disease, we highlight the importance of early diagnosis and surgical treatment as it is a surgically curable disease with a good postoperative prognosis.
脊髓硬膜外蛛网膜囊肿（SEAC）是一种罕见疾病，可导致背痛、神经根病和压迫性脊髓病。它约占脊柱肿瘤的1%。SEAC的确切病因尚不完全清楚；然而，本研究支持该疾病的创伤性病因，此外还支持单向瓣膜作为脑脊液积聚的一种机制。本研究的目的是回顾一名SEAC患者的临床表现、检查、治疗及术后过程。我们报告一例40岁男性患者，有外伤史，患SEAC并在我们科室接受了手术治疗。尽管是罕见疾病，但我们强调早期诊断和手术治疗的重要性，因为它是一种手术可治愈且术后预后良好的疾病。
