摘　　要：目的　充分认识病毒性脑炎多样性的临床及影像表现 ,提高对本病诊断的正确性。方法　CT检查 12例 ,MRI检查 2例 ,CT和MRI均检查者 6例 ,增强检查 9例。结果　CT表现以大小范围不等片状低密度为主 ,多分布于额、颞、顶皮质、皮质下区及侧脑室周围白质区 ,常为多发。单侧发病范围较大时 ,有明显占位效应。MRI表现长T1长T2 信号 ,与同时做CT检查者比较 ,MRI显示病变更清楚。增强扫描病变以无明显强化为主。结论　CT、MRI影像表现与临床紧密结合 。Objective To make a full understanding of the various manifestations of viral encephalitis on clinic and imagery data,and improve its diagnostic accuracy. Methods CT was porformed in 12 cases,MRI in 2 cases,both CT and MRI in 6 cases, and enhanced CT or MRI in 12 cases. Results The lesions prescuted mainly as low density on CT scan and mostly located in front lobe, temporal lobe. Cortices, subcortical and periventricular white matter,usually multipled. It had obvious mass effects when the lesion was larger in one side. The lesion carried long T 1 and long T 2 on MRI.Compare with the patient underwent both CT and MRI, MRI was superior to CT. The lesion mainly showed slight enhancement on contrasted scans.Conclusion The close connection of manifestations on CT,MRI with clinc, can provide important information for clinical diagnosis of viral encephalitis.
