BACKGROUND
Ligamentum flavum cysts are thought to develop due to facet joint hypermobility; however, the etiology of these lesions is not completely elucidated. These cysts may lead to compressive pathologies of the spine requiring surgical intervention.
CASE REPORT
We report the case of a 63-year-old male with chronic back pain and progressive neurogenic claudication for 6 months. He was found to have a ligamentum flavum cyst situated along the dorsal midline of the lumbar spinal canal contributing to spinal stenosis. The patient underwent a decompressive L4 laminectomy and en bloc excision of the ligamentum flavum cyst with complete resolution of his symptoms postoperatively.
CONCLUSIONS
We suggest that chronic mechanical stress leads to degeneration of the ligamentum flavum and contributes directly to cyst formation.
背景
黄韧带囊肿被认为是由于小关节活动过度而形成；然而，这些病变的病因尚未完全阐明。这些囊肿可能导致脊柱的压迫性病变，需要手术干预。
病例报告
我们报告一例63岁男性，有6个月的慢性背痛和进行性神经源性间歇性跛行。发现他在腰椎管背侧中线处有一个黄韧带囊肿，导致椎管狭窄。患者接受了L4减压椎板切除术并整块切除黄韧带囊肿，术后症状完全缓解。
结论
我们认为慢性机械应力导致黄韧带退变并直接促成囊肿形成。
