摘要
目的探讨儿童侧脑室周围白质软化症(PVL)的临床和核磁共振(MRI)特征。方法对36例PVL的临床资料进行回顾性分析。结果胎龄:30～37周22例,38～42周14例。临床表现:肢体瘫痪36例,皮质盲2例,智力低下9例,癫痫10例。MRI表现:病灶形态:斑片状16例,斑点状13例,条纹状7例。部位:半卵圆中心及侧脑室周围白质。病灶信号:呈长T1或等T1,长T2变化。其他:两侧侧脑室体部扩张8例,三角区扩大5例。结论PVL是脑性瘫痪的一个主要原因,MRI是早期诊断PVL的一个主要方法。
Objective To investigate the clinical and MRI characteristic of periventricular leukomalacia(PVL) in children.Method To analysis the clincal data of 36 children with PVL.Result Gestaional age:30～37 weeks in 22 cases, 38～42 weeks in 14 cases;clinical manifestation:paralysis in 36 cases,cortical blindness in 2 cases,mental retardation in 9 cases,epilepsy in 10 caese;MRI manifestation:foci form:patchy areas in 16 cases,punctate areas in 13 cases,streaks in 7 cases.section:symmetric signal abnormalitis were observed in the periventrcular and the subcortical white matter.the signal of the focus:hyperintense/intense on T1 weighted and hyperintense on T2 weighted.others:bilateral ventricular bodies dilatation in 8 cases,trigone dilatation in 5 cases.Conclusion PVL is a main cause of cerebral palsy,especially of spastic paralysis,MRI is a main way to diagnose PVL in early.
