BACKGROUND
Cysts of the ligamentum flavum (LF) are rare occurrences, with only a few cases reported in literature. They are a result of age-related degenerative changes in the LF. The cyst compresses the neural elements and causes neurogenic symptoms. Endoscopic resection of the LF cyst has not been described in literature. In this report, we describe our experience with endoscopic resection of an LF cyst in the L3-L4 region.
CASE DESCRIPTION
A 54-year-old female patient presented with claudication in both lower limbs and evidence on magnetic resonance imaging of a LF cyst in the L3-L4 region compressing the neural elements. The patient underwent full endoscopic resection of the LF cyst through the interlaminar approach from the left side with preservation of facet joints. The postoperative clinical outcomes improved significantly, and postoperative magnetic resonance imaging revealed a complete removal of the cyst.
CONCLUSIONS
Full-endoscopic resection may be considered as a viable option for treatment of LF cyst in the lumbar region.
背景
黄韧带囊肿（LF）较为罕见，文献中仅有少数病例报道。它们是 LF 退行性改变的结果。囊肿压迫神经结构，引起神经性症状。文献中尚未描述 LF 囊肿的内镜切除。在本报告中，我们描述了经皮内镜下切除 L3-L4 节段 LF 囊肿的经验。
病例描述
一名 54 岁女性患者出现双下肢跛行，磁共振成像显示 L3-L4 节段 LF 囊肿压迫神经结构。患者接受了从左侧经椎间孔入路的全内镜 LF 囊肿切除术，保留了关节突关节。术后临床结果显著改善，磁共振成像显示囊肿完全切除。
结论
全内镜切除可作为治疗腰椎 LF 囊肿的一种可行方法。
