摘　　要：目的研究儿童脑室周围白质软化症（PVL）的CT与相关临床表现。方法回顾性分析18例PVL患儿的CT与临床资料。结果PVL的临床表现为：①肢体瘫痪，可为双侧肢体瘫痪，四肢瘫痪，一侧肢体瘫痪。②皮质盲。③智力低下。④癫痫。⑤共济失调。CT表现：①侧脑室周围白质减少。②侧脑室体旁白质内点片状低密度灶。③侧脑室扩大，形态不规则。④脑沟增深，皮质下灰质逼近侧脑室壁。结论由于对早产儿缺氧缺血性脑病的临床救治工作的进展，存活儿会逐渐增多。而且CT检查的普遍开展，PVL的发现会越来越多。CT是诊断PVL的重要方法。充分结合临床资料正确诊断PVL并不困难。Objective To study the CT and clinical features of periventricular leukomalacia in children （PVL）. Methods CT and clinical features in 18 cases with PVL were retrospectively analyzed. Results The clinical features of PVL were：（1）palsy, of one side, or two sides, Or four limbs ; （2）the cortical blind ; （3）amentia; （4）epilepsy; （5）incoordination. CT features of PVL were ： （1） decrease of the periventricular white matter;（2）pieces of low density in the periventricular white matter; （3）the lateral ventricle expanded and irregular;（4）the cerebric fossa were much more deep, and the hypophloeodal grey matter approach to the wall of the lateral ventricle. Conclusion The livability gradually increased as a result of the progress in the clinical treatments for premature with hypoxic - ischemic encephalopathy, and more and more patients with PVL will be found owing to the prevalent application of CT. CT scans is the main method in diagnosis of PVL, closely contacted with the clinical features can easily diagnose PVL.
