The operative and magnetic resonance image (MRI) findings of 25 patients with the diagnosis of lipomyelomeningocele and/or tethered cord were compared. Postoperative MRI scans of eight patients, five of whom were in stable condition, were also compared with the preoperative studies. In this review there was one false negative MRI scan and four MRI scans in which the relationship of the lipoma to the conus or filum was not demonstrated accurately. In six patients, incidental intramedullary cystic lesions at the conus were identified by MRI scan. All eight postoperative (1 month to 2 years) scans demonstrated no change in the level of the conus from the preoperative study. MRI is an accurate screening modality in the initial diagnosis of occult spinal dysraphism. MRI was not useful in the postoperative evaluation of lipomyelomeningocele and the tethered cord, since the caudal, posterior displacement of the conus was unchanged in all studies.
对25例诊断为脂肪脊髓脊膜膨出和/或脊髓栓系的患者的手术及磁共振成像（MRI）结果进行了比较。还将8例患者的术后MRI扫描结果与术前研究进行了比较，其中5例病情稳定。在本综述中，有1例MRI扫描结果为假阴性，4例MRI扫描未准确显示脂肪瘤与圆锥或终丝的关系。6例患者通过MRI扫描发现圆锥处有偶然的髓内囊性病变。所有8例术后（1个月至2年）扫描结果显示，圆锥水平与术前研究相比无变化。MRI是隐匿性脊柱裂初始诊断中的一种准确筛查方式。MRI在脂肪脊髓脊膜膨出和脊髓栓系的术后评估中无用，因为在所有研究中圆锥的尾侧、后方移位均未改变。
