摘要
目的:总结腰椎椎体后缘软骨结节所致腰椎管狭窄症的临床、影像学表现及诊断要点,探讨有关的发病因素。方法:对32例腰椎椎体后缘软骨结节所致腰椎管狭窄症的临床表现、影像学特征进行分析。结果:32例均有间歇性跛行,多以腰腿痛为主诉就诊,9例推拿按摩后症状加重。X线腰椎侧位片见病变椎体(以腰4、5为主)后下(或上)角有骨缺损及该区有游离小骨块突入椎管内;典型的影像学改变为:(1)椎体后上缘类圆形骨质缺损,边缘较致密硬化;(2)缺损后方有一骨块突入椎管(游离或部分与椎体相连);(3)硬膜囊及神经根受压,可伴有椎间盘突出。结论:CT有特征性表现,能为制订治疗方案提供可靠依据。
Objective :To summarize the clinical and imaging characteristics of lumbar spinal canal stenosis caused by lumbar posterior marginal intraosseous cartilaginous node (LPMN),and to discuss its related etiological factors. Methods:The clinical manifestations and imaging characteristics of 32 cases with lumbar spinal canal stenosis caused by LPMN were analysed. Results:The typical imaging findings included: (1)focal defect in the posterior superior margin with sclerotic edge; (2)the defect foci which appeared the bony fragment sticking out the spinal canal; (3)compression of the dural sac and nerve root,mostly with lumbar discprotrusion.Conclusion:CT exanmiation is typical,and can provide a valuabe information for planning the treatment protocol.
