An 8-year-old girl showed symptoms of encephalitis during acute Epstein-Barr virus (EBV) infection. The diagnosis of EB virus infection was made by changes in the titres of EB virus-specific antibody. Cranial MRI demonstrated abnormal low and high signal intensities in the striatal body (putamen and caudate nucleus) on T1-weighted and T2-weighted images, respectively, during the acute phase. These abnormal findings had almost completely resolved 1 month later. EBV infection should be considered when lesions are localised to the basal ganglia.
一名8岁女孩在急性爱泼斯坦-巴尔病毒（EBV）感染期间出现脑炎症状。EB病毒感染的诊断是通过EB病毒特异性抗体滴度的变化做出的。急性期头颅MRI显示，在T1加权像和T2加权像上，纹状体（壳核和尾状核）分别出现异常的低信号和高信号强度。1个月后，这些异常表现几乎完全消失。当病变局限于基底神经节时，应考虑EBV感染。
