小儿脑性瘫痪的CT和MR诊断

CT and MR Diagnosis of Children Cerebral Palsy

目的讨论CT和MR对小儿脑性瘫痪诊断中的价值。方法对229例小儿脑性瘫痪回顾性分析临床表现及CT和MR征象。结果 229例小儿脑性瘫痪中,157例为CT诊断,72例为MR诊断,CT对小儿脑性瘫痪诊断的阳性率为54.14%,MR对小儿脑性瘫痪诊断的阳性率为68.06%,CT和MR诊断阳性率差异有统计学意义(P<0.05);26例为脑软化灶,21例双侧额部硬膜下积液,17例为脑灰白质萎缩,13例为脑积水,11例为脑炎及脑膜炎,7例为胼胝体发育不良,7例为脑多发钙化斑,6例为脑裂畸形,6例为脑贯通性畸形,4例为脑缺血灶,4例为脑白质变性,4例为无脑汇或巨脑汇畸形,3例为脑灰白质移位,3例为dandy-walker,2例为sturge-wenber。结论 CT和MR能准确诊断小儿脑性瘫痪,对患者预后有很大的评估价值,MR对本病诊断比CT更有价值。

Objective To discuss the value of CT and MR in diagnosing children Cerebral palsy. Methods Clinical manifestations and CT and MRI signs of 229 cases with children Cerebral palsy were analyed retrospectively. Results In the 229 cases with children Cere- bral palsy, 157 cases were diagnosed by CT, and 72 cases were diagnosed by MRI. The positive diagnosis rates of CT and MRI were 54.14% and 68.06%, and the differences of positive diagnosis rates between CT and MRI had statistical significance￡P〈0.05￡. 26 cases were encephalomalacia： 21 cases were subdural effusion of bilateral flontal part： 17 cases were White and gray matter atroppyim 13 cases were hydrocephalus; 11 cases werc encephalitis and meningitis; 7 cases were corpus callosum hypoplasia; 7 cases were cerebral multiple calcified plaque： 6 cases were Schizencephaly; 6 cases were penetrating brain malformation, 4 cases were brain ischemia： 4 cases were myelinopathy; 4 cases were no or giant brain meeting malformation; 3 cases were ectocinerea and alba ectopia; 3 cases were dandy-walker; 3 cases were sturge-wenber. Conclusion CT and MR can diagnose children Cerebral pals accurately, and have great evaluation value for prognosis of patients. MR has greater value than CT.
