摘要
目的:探讨MRI对神经鞘膜瘤的诊断价值。方法:对13例椎管内神经鞘膜瘤的影像资料进行分析。其中颈段5例,胸段6例,腰段2例。13例术后均行病理检查。结果:所有病例在T2WI上均呈高信号,T1WI上略高信号4例,等信号9例。Gd-DTPA增强明显均匀强化8例,明显不均匀强化5例。有椎弓根骨质压迫局限吸收5例,8例明显均匀强化大体病理呈灰白色,5例明显不均匀强化呈灰黄色,所有病例均有包膜。结论:MRI﹑CT、X线平片比较:(1)显示肿瘤病变MRI优于CT及X线平片。(2)显示椎弓根局限骨质吸收CT优于MRI。(3)术前评估肿瘤范围,MRI有明显优势。
Objective：To investigate the diagnostic value of MRI on intraspinal neurinoma.Methods：The imageologic data of 13 patients with intraspinal neurinoma were retrospectively analyzed,which including 5 cases in cervical segments,6 cases in thoracic segments and 2 cases in lumbar segments.13 cases received the pathological examination after operation.Results：All patients showed high signal in T2WI and T1WI,slightly higher signal existed in 4 cases and equal signal in 9 cases.Homogeneous enhancement of Gd-DTPA was significantly enhanced in 8 cases,5 cases showed markedly enhanced heterogeneity.5 cases had local absorption of vertebral pedicle bone compression,8 cases had obvious homogeneous enhancement which showed off-white in macropathology,5 cases had significant heterogeneity enhancement which showed grayish yellow.All cases had envelops.Conclusion：Comparison of MRI,X ray and CT：（1）MRI is superior to CT and X-ray in demonstrating the tumor lesions;（2） CT is superior to MRI in demonstrating the local absorption of vertebral pedicle bone;（3）MRI has obvious superiority in the preoperative evaluation of the tumor range.
