A previously healthy 45-year-old woman presented with ligamentum flavum hematoma manifesting as radicular leg pain. Neurological examination findings were consistent with L-5 root compression. An old hematoma inside the degenerated ligamentum flavum was drained. The cyst showed no connection to the facet joint. Complete resection of the mass was performed, resulting in excellent pain relief. The most common cystic lesion in the lumbar spine is synovial cyst associated with the facet joints, but ligamentum flavum hematoma should be included in the differential diagnosis. The preoperative diagnosis can be based on computed tomography and magnetic resonance imaging findings of degenerative thickening of the ligamentum flavum associated with a fluid component.
一名既往健康的45岁女性因黄韧带血肿就诊，表现为腿部放射性疼痛。神经学检查结果与L-5神经根受压相符。对退变黄韧带内的陈旧性血肿进行了引流。囊肿与小关节无连接。对肿物进行了完整切除，疼痛得到了显著缓解。腰椎最常见的囊性病变是与小关节相关的滑膜囊肿，但黄韧带血肿也应列入鉴别诊断。术前诊断可基于计算机断层扫描和磁共振成像显示的黄韧带退变增厚并伴有液体成分的表现。
