摘要
目的 探讨病毒性脑炎(下称病脑)不同病情临床影像学改变与临床的关系。方法 对132例不同病情病脑头颅CT、MRI与临床表现进行分析研究。结果 头颅CT检查122例,异常74例,异常率60.65%。MRI检查16例,异常15例,异常率93.75%。MRI的改变比CT更加明显。病情轻者CT基本正常,但MRI则可有改变。病情中度者以累及灰质为主,表现为灰质肿胀。病情重者同时累及灰、白质。极重度者可伴脑出血。临床疗效好者影像学改变轻,疗效差者影像学改变明显,并发症与后遗症发生率高。结论 病脑患儿头颅CT、MRI检查,尤其MRI对该病的诊断、病情轻重及预后有重要意义。
Objective To investigate the relationship between the changes of the cranial CT and MRI image and clinical presentation of different degree of viral encephalitis in Children. Methods 132 children with viral encephalitis in different degree received cranial CT scan or MRI examination as well as clinical analysis. Results 74 showed abnormal findings in 122 chidlren examined by cranial CT. The abnormal rate was 60.65% . 15 showed abnormal findings in 16 children examined by cranial MRI. The abnormal rate was 93.75% . The changes in MRI were more obvious than in CT. MRI findings could be abnormal in mild cases whose CT findings were normal. Brain cinereum were found abnormal in moderate cases, presenting as cinereum edema. Both black and white matter were found abnormal in serious cases. Brain hemorrhage could be found in extremely serious cases.Conclusion Only small changes imaging existed in children with good response while marked changes could occurred in children with poor response and high rate of occurrence of complications and sequelas. These indicated that CT scan and MRI examination, especially MRI examination had great significance in diagnosis, degree and prognoses predicting of children's viral encephalitis.
