| 摘 要： | 笔者对6例临床确诊为单纯疱疹性脑炎病人进行了MRI检查,其中5例初次MRI检查有阳性所见。在MRI的T_1WI上病变为低信号区,T_2WI为高信号区,可侵犯四个脑叶,其中最常侵犯颞叶。脑岛、基底节及脑白质也可受累。4例出现轻度肿块效应。与CT比较,MRI在诊断单纯疱疹性脑炎方面优于CT,可显示CT未能发现的隐匿病灶。

| Abstract: | 6 patients with clinically diagnosed herpes simplex encephalitis (HSE) were examined by MRI. There were positive MRI findings in 5 patients. The findings of MRI of foci were low intensity on T1WI and high intensity on T2WI. Of the four cerebral lobes,temperal lobes were the most commonly affected regions . The insula,basal ganglion and white matter may also be involved. Mild mass effect was present in 4 cases. With comparison, MRI was superior in diagnosis of HSE to CT, and may show the occult foci undetected by CT. |
