摘要： 目的探讨早产所致脑性瘫痪的磁共振成像(MRI)特征。方法回顾性分析16例早产所致脑性瘫痪患儿的临床资料和颅脑MRI图像，并以同期16例年龄匹配的正常小儿头颅MRI作对照。结果16例均诊断为脑性瘫痪痉挛型双瘫。16例早产所致脑性瘫痪患儿在MRI上表现为脑室周围白质在T2WI上的异常高信号、脑室周围深部白质减少、侧脑室变大伴或不伴变形，胼胝体萎缩。上述特点符合脑室周围白质软化(PVL)。结论PVL是早产所致脑性瘫痪的MRI特征性表现，这有助于脑性瘫瘫病因和类型的判断。

Abstract: ObjectiveTo study the characteristic findings on MRI in children surviving premature delivery with cerebral palsy.MethodsThe clinical data and MR imaging in 16 cases surviving premature delivery with cerebral palsy was retrospectively analyzed, compared with 16 healthy and age-matched controls.Results16 cases were final diagnosed as cerebral palsy with spstic diplegia. MRI features of children surviving premature delivery with cerebral palsy included abnormally high signal intensity in the periventricula white matter on T2WI, marked loss of periventricular deep white matter, ventriculomegaly with or without irregular ventricular outline and atrophy of the corpus callossum. These features were consistent with periventricular leukomalacia(PVL).ConclusionPVL was the characteristic findings on MRI in children surviving premature delivery with cerebral palsy. The characteristic findings of PVL was useful in determining the etiology and type of cerebral palsy in children.
