目的 探讨小儿脊髓栓系综合征 (tetheredcordsyndrome ,TCS)的螺旋CT(SpiralCT ,SCT)影像学特点及诊断价值。方法 回顾性分析手术确诊的TCS患儿 13 6例 ,对其SCT平扫及多平面重建 (multiplannerreformation ,MPR)的影像特点与临床表现、手术所见进行对照分析。结果 13 6例TCS患儿中圆锥均低于L3 甚至达S2 以下 ,合并脊髓骨性纵裂 2 4例、脂肪瘤 61例、终丝增粗脂肪变 11例、脊髓空洞症 9例、椎体畸形 2 6例。 13 6例TCS患儿伴有脊柱裂 12 9例 (95 % ) ,其中包括 18例隐性脊柱裂 ,111例显性脊柱裂。通过SCT/MPR均能获得较满意的图像。结论 SCT/MPR能为手术提供完整的资料 ,是继MRI、B超之后诊断TCS的又一重要方法
Objective To investigate the imaging features and diagnostic value of Spiral CT (SCT) in pediatric tethered cord syndrome (TCS). Methods A retrospective analysis was performed on 136 children with TCS confirmed by surgery. The imaging features, clinical manifestations and surgical findings of SCT and multiplanner reconstruction (MPR) were analyzed retrospectively. Results The cones in 13 children with TCS were all lower than L3 and even below S2. There were 24 cases with spondylostenal longitudinal lobe, 61 cases with lipoma, 11 cases with terminal fat hyperplasia, 9 cases with syringomyelia, Malformations in 26 cases. Thirteen cases of pediatric patients with TCS had spina bifida in 12 9 cases (95%), including 18 cases of latent spina bifida and 111 cases of dominant spina bifida. By SCT / MPR can get more satisfactory image. Conclusion SCT / MPR can provide complete information for surgery and is another important method for diagnosing TCS after MRI and B ultrasound
