Abstract：
Spinal extradural arachnoid cysts are an uncommon condition and their exact causative triggers are still unclear. They appear to be extradural arachnoid outpouchings that connect to the intraspinal subarachnoid region via a little dura defect. These cysts are most commonly seen in the thoracic spine, followed by the lumbosacral junction. Compression of the spinal cord or nerve roots leads to the development of the symptoms. The most morbid symptom associated with these compressing extradural cysts is paresthesia. Numerous theories have been proposed about their origins, and the related conditions include spinal trauma, spina bifida, and the lymphedema-distichiasis syndrome. Their position in the spine influences the symptoms manifested. The diagnosis is made via MRI. Surgery is only performed on individuals with neurological impairment, and treatment is based on the clinical presentation. The preferred course of therapy is total surgical excision. We present a case that involves the successful surgical removal of an extradural spinal arachnoid cyst in a 10-year-old girl. Given the rarity of this pathology, its wide array of presenting symptoms, and the successful therapeutic protocol that was followed in this particular case, we believe this article shall prove beneficial to the medical fraternity.
摘要：
脊髓硬膜外蛛网膜囊肿是一种罕见的疾病，其确切的病因仍不清楚。它们似乎是硬膜外蛛网膜外袋，通过一点硬脑膜缺损连接到椎管内蛛网膜下区。这些囊肿最常见于胸椎，其次是腰骶骨交界处.脊髓或神经根的压迫导致症状的发展。与这些压迫性硬膜外囊肿相关的最病态症状是感觉异常。关于它们的起源已经提出了许多理论，相关的疾病包括脊柱外伤，脊柱裂,和淋巴水肿-淋巴瘤综合征.它们在脊柱中的位置影响所表现的症状。通过MRI诊断。手术只对有神经损伤的人进行，治疗是基于临床表现。优选的治疗过程是完全手术切除。我们介绍了一个病例，该病例涉及成功手术切除一名10岁女孩的硬膜外脊髓蛛网膜囊肿。鉴于这种病理学的罕见性，它表现出各种各样的症状，以及在这种特殊情况下遵循的成功治疗方案，我们相信这篇文章将对医学界有益。
