BACKGROUND
Sacral cysts are classically divided into Tarlov cysts and meningeal diverticula. However, the pathogenesis of sacral cysts remains unclear. This study aimed to clarify a novel type of sacral extradural spinal meningeal cyst with a specific arachnoidal structure.
METHODS
Nine patients with prophylactic diverticula were included in the study. All patients underwent MRI preoperative reconstruction and traditional neck transfixation.
RESULTS
All patients presented with more than one symptom. The major symptom was lower extremity pain, followed by lower extremity numbness (77.8%, 7/9), lower extremity weakness (55.6%, 5/9), bowel/bladder and sexual dysfunction (55.6%, 5/9), and tenesmus (22.2%, 2/9). After long-term follow-up, the outcome was classified as improved in 9 patients (100%).
CONCLUSIONS
The clinical findings of this study illustrate a special subtype and may help explain the mechanism of sacral cyst formation.
背景
骶骨囊肿通常分为 Tarlov 囊肿和脑膜憩室。然而，骶骨囊肿的发病机制仍不清楚。本研究旨在阐明一种具有特定蛛网膜结构的新型骶骨硬脊膜外脊髓脑膜囊肿。
方法
本研究纳入了 9 例预防性憩室患者。所有患者均接受了 MRI 术前重建和传统的颈部贯穿固定。
结果
所有患者均出现了不止一种症状。主要症状是下肢疼痛，其次是下肢麻木（77.8%，7/9）、下肢无力（55.6%，5/9）、肠/膀胱和性功能障碍（55.6%，5/9）以及里急后重（22.2%，2/9）。长期随访后，9 例患者（100%）的结果被归类为改善。
结论
本研究的临床发现说明了一种特殊的亚型，可能有助于解释骶骨囊肿形成的机制。
