【摘要】 目的:探讨脊髓栓系综合征(TCS)的MR I特点及其临床价值。方法:回顾性分析38例经手术病理证实的脊髓栓系综合征的MR I表现,并与手术所见及临床对比。结果:TCS均表现为脊髓低位;椎管内脂肪瘤9例,皮样囊肿4例,畸胎瘤2例,双干脊髓2例,脊髓空洞症6例,脊髓纵裂2例,脂肪脊髓脊膜膨出13例;其中7例无临床症状为查体时发现。MR I表现与临床手术所见相符。结论:MR I对脊髓栓系综合征确诊具有重要价值,能明确显示脊髓圆锥的位置、形态及伴发畸形,为手术提供可靠的依据,提高手术疗效。更多还原

【Abstract】 Objective:To study the features of MRI in TCS,and the relationship between the diagnostic value of MRI and clinical symptoms.Methods:MRI appearance,clinical features and surgical finding from 38 cases of TCS which proved by surgery and pathology were analyzed retrospectively.Results: In all patients,the levels of the tips of the conus were below the mid L2 vertebral body.including in tradural lipoma(n=8),dermoidcyst(n=4),teratoma(n=2),double stem spinal cord(n=2),5diastematomyelia(n=2),myelomeningocele(n=13).All cases were spinal dysraphism,6 cases were asymptomatic and diagnosis of TCS was made by regular examination.MRI features were consistent with the findings in operation and symptom.Conclusions: MRI examination is of important value in the diagnosis of TCS,which can nicely reveal the position and the shape of spinal cord conus.MRI can also show the TCS associated malformation and provide the dependable basis f orsurgical operation.更多还原
