摘要
作者报告17例ChiariI型畸形,全部行头颈部矢状及横轴位扫描,其中53%(9/17)伴有脊髓空洞症。53%(9/17)伴发颅颈交界处骨发育异常。8例发现身体其它部位先天发育畸形。头颈部矢状T1加权像能清楚地显示小脑扁桃体疝、脊髓空洞症及合并的颅颈交界处骨发育异常。探讨其发病机制及诊断标准。
7 cases of Chiari Ⅰ type
malformation are reported.A sagittal multisectionand axial multisection of head neck were
performed in all cases.53%( 9 /17)patients with syringohydromyelia. 53%(9 /17)were associated
with bone anomal- ies of craniovertebral junction, The congenital and developmental
anomaliesof others parts were founded in 8 cases. T1 weighted imaging of head and neckin
sagittal can demonstrate optimally cerebellar tonsil herniation, syringohy- dromyelia, and
bone anomalies of craniovertebral junction. The mechanism and diagnostic standard of this
disease are discussed.
