【摘要】：目的总结儿童伴可逆性孤立胼胝体压部病变轻型脑炎(MERS)磁共振(MRI)表现及临床特点,并分析可能病因。方法回顾总结2012年1月至2014年5月山西省儿童医院7例MERS患儿临床资料及MRI表现,分析其表现及特点。结果 7例患者中男4例、女3例,年龄2~14岁;临床表现包括发热5例(71.4%)、消化道症状6例(85.7%)、睡眠增多4例(57.1%)、抽搐3例(42.9%)、头晕1例(14.2%)、颈抵抗阳性1例(14.2%)。脑脊液常规生化正常。MRI表现均为仅见胼胝体压部正中稍长T1稍长T2信号,DWI呈高信号,ADC图呈低信号。5例呈居中带状,2例呈居中卵圆形。7例患儿经抗感染等对症支持治疗后病情痊愈出院,病程最短8 d,最长19 d。复查MRI示胼胝体压部病变消失。结论儿童MERS临床表现多为发热、消化道症状、睡眠增多或抽搐等,有其特征性MRI表现,属于可逆的细胞毒性水肿,预后良好。
[Abstract]:Objective to summarize the magnetic resonance imaging (MRI) findings and clinical features of mild encephalitis (MERS) in children with reversible solitary splenic lesions of corpus callosum. Methods from January 2012 to May 2014, the clinical data and MRI findings of 7 cases of MERS in Shanxi Children's Hospital were analyzed retrospectively. Results there were 4 males and 3 females aged 214 years. The clinical manifestations included fever in 5 cases, digestive tract symptoms in 6 cases, symptoms of digestive tract in 6 cases, increased sleep in 4 cases, increased sleep in 4 cases, increased sleep in 4 cases, increased sleep in 4 cases, convulsions in 3 cases, dizziness in 1 case, dizziness in 1 case, cervical resistance in 1 case, positive cervical resistance in 1 case, and normal biochemical characteristics in cerebrospinal fluid. MRI showed only the middle and slightly longer T1 of corpus callosum. The patients with slightly longer T 2 signal intensity and DWI showed high signal intensity and low signal intensity. 5 cases showed middle band shape and 2 cases showed middle oval shape. 7 cases were cured and discharged after treatment with anti-infection and other symptomatic support. The shortest course of disease was 8 days and the longest was 19 days. MRI examination showed that the lesion of corpus callosum disappeared. Conclusion the clinical manifestations of MERS in children are fever, gastrointestinal symptoms, increased sleep or convulsions, which have characteristic MRI manifestations and belong to reversible cytotoxic edema. The prognosis is good.
