小儿脊髓神经管缺陷的MRI诊断价值(附55例报告)

The MRI diagnostic value of child spinal neural-tube defects(report of 55 cases)

目的:回顾55例小儿脊髓神经管缺陷的MRI表现并复习文献,探讨该病的MRI诊断价值。方法:男33例,女22例,使用1.5T超导MR机行病变区脊柱扫描。结果:脊髓脊膜膨出12例;脊膜膨出1例;脂肪脊髓脊膜膨出9例;终丝脂肪瘤4例;硬膜内脂肪瘤3例;背侧上皮窦12例;原发性脊髓栓系综合征4例;脊髓纵裂4例;神经肠源性囊肿2例;术后复查4例。结论:MRI是诊断该病最有效的无创检查方法,可以清晰显示脊髓栓系、脊髓神经组织粘连及压迫以及脊髓空洞积水,评估脂肪瘤的范围,进行脊髓纵裂分型。

Objective：To review MRI features of 55 children with spinal neural-tube defects and the literature,then evaluated the diagnostic value of spinal neural-tube defects by MRI.Methods：55 children ranged from neonate to 18 years-old.33 children were males,22 children were females.All of spines were scanned by 1.5 T MR machine.Results：MRI diagnoses were as follow：12 cases with myelomeningocele,1 case with meningocele,9 cases with lipomyelomeningocele,4 cases with lipoma of filum terminale,3 cases with intradural lipoma,4 cases with diastematomyelia,4 cases with primordial TCS,2 cases with neuroenteric cyst,12 cases with dorsal dermal sinus,4 cases with postoperative check.Conclusion：MRI was the most effective methed and was woundless methed to diagnose spinal neural-tube defects.It could display tethered cord and syringohydromyelia clearly;evaluate that the spinal cord was oppressed comprehensively.It could assess the range of lipoma.Fine classification of diastematomyelia might benefit the surgeon if operation was feasible.
