【摘要】 目的探讨MRI对脊髓栓系综合征(TCS)合并脂肪瘤患者脂肪瘤内神经纤维的显示及MRI分型与临床表现相关性研究。方法回顾性分析23例MRI诊断为脊髓栓系合并脂肪瘤患者脂肪瘤内神经纤维的MRI图像与临床表现。结果本组共23例TCS合并脂肪瘤患者MRI均可以明确神经纤维位置、走行及毗邻关系等解剖学特征。MRI简单型共7例,包括单纯脂肪瘤1例、粘连型6例;MRI复杂型共16例,包括包绕型4例,包绕并融合型12例。MRI显示复杂型TCS合并脂肪瘤患者较简单型患者更易出现明显临床症状(P=0.007)。结论 MRI可清晰显示TCS合并脂肪瘤的分型及其内的神经纤维,其对手术具有重要的价值。更多还原

【Abstract】 Objective To study the value of MRI in depicting the different types of tethered cord syndrome(TCS) with lipomas.Methods The clinical presentation and MRI of 23 patients with TCS and lipoma were retrospective analyzed.Results The location and course of nerve fibers as well as the adjacent tissue were-identified.The TCS were classified as simple(7) including 1 simple lipoma and 6 adhesive lipomas,or complicated(16) including 4 encasing and 12 mixed encasing and fusion lipomas.Patients with complicated lipomas had more severe symptoms.Conclusion MRI can clearly demonstrate the nerve fibers and helps to classify TCS with lipomas for surgical planning.更多还原
