脊柱闭合不全的MR影像诊断（二）隐性脊柱闭合不全

MR Imaging of Spinal Dysraphism(II)Closed Spinal Dysraphism

本组隐性脊柱闭合不全包括脊髓纵裂２例、侧位脊膜膨出１例、脂肪瘤６例、终丝脂肪瘤４例、胆脂瘤５例、脊髓低位９例、肠源性囊肿１４例和骶骨发育不良２例。ＭＲ对隐性脊柱闭合不全的诊断具有较高的价值。矢状面图像可清楚地显示病变的全貌。在诊断脊髓低位和肠源性囊肿时，横断面检查十分重要。

Closed spinal dysraphism in this group included 2 cases of diastematomyelia, l lateral thoracic meningocele. 6 spinal liporna,4 lipoma of filum terminale,5 epidermoid, 9 tethered cord,14 enterogenous cyst and 2 sacral dysplasia,It is very useful to study these abnormalities with MRI, espe-cially on sagittal ilnage. Tethered cord and enterogenous cyst are best delineated on axial images.
