摘要
目的 :提高对腰椎后缘软骨结节CT表现的认识以避免误诊。方法 :对 2 1例腰椎后缘软骨结节的CT资料进行分析 ,9例与常规X片比较。结果 :CT特点为 :①椎后缘骨质缺损 ,密度与椎间盘相似 ,周边硬化。②缺损区后壁有突入椎管骨块。③多伴有椎间盘突出 ( 13 /2 1)。结论 :CT能明确诊断腰椎后缘软骨结节 ,并为制订治疗方案提供可靠依据。
Objective:To improve the recognition of the CT findings of lumbar posterior marginal intraosseous cartilaginous node (LPMN), in order to avoid misdiagnosis. Mothods:CT manifestations of 21 patients with LPMN were analysed. Results:CT characteristics were as follows:①there was a defect at the posterior margin of the affected vertebral body, the density of which was similar to that of vertebral disc, and a sclerotic ring was found around the nodule. ②a bony fragment was found behind the defect protruding into the spinal canal. ③In most of the cases accompanied lumbar disc herniation (13/21) was found. Conclusions:CT scans can provide reliable evidence for diagnosis of LPMN and is helpful for planning treatment protocol.
