Degenerative changes in the lumbar spine can be followed by cystic changes. Most reported intraspinal cysts are ganglion or synovial cysts. Ligamentum flavum pseudocyst, as a cystic lesion in the lumbar spine, is a rare and unusual cause of neurologic signs and symptoms and is usually seen in elderly persons (due to degenerative changes). They are preferentially located in the lower lumbar region, while cervical localization is rare. Complete removal of the cyst leads to excellent results and seems to preclude recurrence. We report the case of a right-sided ligamentum flavum cyst occurring at L3-L4 level in a 70-year-old woman, which was surgically removed with excellent postoperative results and complete resolution of symptoms. In addition, we discuss and review reports in the literature.
腰椎退行性改变可继发囊性改变。大多数报告的椎管内囊肿为神经节囊肿或滑膜囊肿。黄韧带假性囊肿是一种少见的腰椎囊性病变,是引起神经体征和症状的不常见原因,通常见于老年人(因退行性改变所致)。它们多位于下腰椎区域,颈椎少见。囊肿完整切除可获得良好效果,似乎可避免复发。我们报告了一例 70 岁女性 L3-L4 水平右侧黄韧带囊肿,手术切除后效果极佳,症状完全缓解。此外,我们还讨论和回顾了文献中的报告。
