Spinal extradural arachnoid cysts are rare expanding lesions in the spinal canal. Enlargement may cause progressive signs and symptoms caused by spinal cord compression. They are associated with trauma, surgery, arachnoiditis, and neural tube defects. Most nontraumatic spinal extradural arachnoid cysts are thought to be congenital.
Case report and literature review.
A 9-year-old boy with mild paraparesis was found to have an extradural multiloculated arachnoid cyst with fibrous septa at T4-L3 levels and anterior compression and displacement of the spinal cord.
Definitive treatment of arachnoid cyst entails radical cyst removal and dura cleft repair. Formation of a postoperative cerebrospinal fluid fistula may require external lumbar drainage.
脊髓硬膜外蛛网膜囊肿是椎管内罕见的扩展性病变。囊肿扩大可能导致因脊髓受压引起的进行性体征和症状。它们与创伤、手术、蛛网膜炎和神经管缺陷有关。大多数非创伤性脊髓硬膜外蛛网膜囊肿被认为是先天性的。
病例报告及文献复习。
一名9岁轻度双下肢轻瘫男孩被发现患有硬膜外多房性蛛网膜囊肿，囊肿位于T4 - L3水平，有纤维分隔，脊髓前方受压并移位。
蛛网膜囊肿的确切治疗需要彻底切除囊肿并修复硬脑膜裂孔。术后脑脊液瘘的形成可能需要进行腰大池引流。
