| 摘 要： | 报告5例单纯疱疹病毒性脑炎的CT和MR检查结果。并结合国外文献对其影像学特点进行讨论。本病首先累及颞叶,单侧或双侧。与豆状核外缘之间分界清楚为其特征性表现。部分病例可向额叶和枕叶发展。CT平扫为低密度,MR检查具有长T_1和长T_2的特点,在T_2加权图表现为高信号。不增强或线状增强,个别可呈环状增强。病变严重者可有轻度占位效应,病变区内可见小灶状出血。 |

| Abstract: | CT and MR findings of five cases of herpes simplex encephalitis (HSE) were presented. The characteristic CT and MR appearances of HSE were discussed. Early involvement is in the temporal lobe (unilateral or bilateral) which may later extend to involve frontal or occipital lobes. Abrupt transition to normal area at the lataral margin of the lenticular nucleus is the characteristic feature of HSE. CT finding is hypodense and MR T2-Weighted shows sbnormal hyperintensity in the lesion area. The pattern of HSE on enhanced CT and MR may be absent or linear enhancement. The mass effect and focal hemorrhage may be encountered in some cases. |
