摘要：

目的 探讨CT和MRI对急性I型单纯疱疹病毒性脑炎（HSE）的早期诊断价值。方法 收集11例临床确诊为急性Ⅰ型HSE的早期病例的临床资料，对CT和MRI表现进行分析和比较。结果 HSE早期病例影像学表现按侵犯部位分为两种类型，侵犯基底节、丘脑、脑干的患者主要表现为“基底节突显”征；侵犯大脑额颞叶皮髓质区的患者主要表现为“刀切征”。结论 CT和MRI有助于对HSE的早期诊断。

Abstract:

Objective To explore the value of CT and MRI in the early diagnosis of acute type I Herpes simplex encephalitis (HSE). Methods The clinical data of eleven patients with HSE in early stage were collected, and the manifestations in CT and MRI were analysed. Results The imaging findings of HSE in early stage were divided into two types. The lesions involved basal ganglia, thalamus and brainstem were characterised by “basal ganglia standing out” sign, while those in frontal and temporal lobe were presented as “knife-cutting” sign. Conclusion MRI and CT play an important role in the early diagnosis of HSE.
