目的:分析探讨儿童病毒性脑炎的磁共掁成像(MRI)影像特点。方法:回顾性分析2013年1月-2014年1月我科确诊儿童病毒性脑炎患者25例;男13例,女12例;年龄2~13岁,平均年龄6.7岁。影像学检查时间在病程的2~15 d。均对患者行头颅MRI平扫。统计头颅MRI平扫中累及头颅不同部位的病例数,并分析病灶的分布特点。结果:25例中MRI平扫均有阳性发现。累及基底核区22例、丘脑12例、脑干区8例、大脑半球3例、小脑2例,其中多发病灶22例。结论:儿童病毒性脑炎病灶较小且成多发特点,好发于基底核区、丘脑及脑干区。
Objective: To analyze the magnetic resonance imaging (MRI) features of viral encephalitis in children. Methods: From January 2013 to January 2014, 25 cases of children with viral encephalitis were diagnosed retrospectively. There were 13 males and 12 females, aged from 2 to 13 years with a mean age of 6.7 years. Imaging examination time in the course of 2 ~ 15 d. Patients were skull MRI scan. Statistical skull MRI plain scan involved in different parts of the head of the number of cases, and analysis of the distribution of lesions. Results: 25 cases of MRI scan were positive findings. Involved in the basal ganglia in 22 cases, 12 cases of thalamus, brain stem area in 8 cases, 3 cases of cerebral hemisphere, 2 cases of cerebellum, including multiple lesions in 22 cases. CONCLUSIONS: Children with viral encephalitis have a lesser and multiple lesion with predilection in the basal ganglia, thalamus and brainstem area.
