摘要
目的 :探讨急性播散性脑脊髓炎的影像学特点。材料与方法 :36例脑炎患者行CT检查 ,15例行MR检查 ,34例为实验室检查证实 ,2例为手术病理证实。结果 :CT表现为脑皮质、白质单发或多发斑片状低密度影 ;MR表现为长T1长T2异常信号 ,部分病灶T1WI呈高信号 ,病变以白质区为著 ,大小不等 ,两颞叶多发 ,可累及脑岛、海马、基底节、脑干、小脑 ,增强扫描大多无明显强化或轻度斑片状强化、脑回样强化。结论 :CT及或MR平扫增强能为脑炎的诊断提供重要的信息 ,尚需结合临床以除外脑梗塞及脑肿瘤以及中毒性脑病。
Purpose:To discuss the image feature of acute disseminated encephalomyelitis on CT/MR.Materials and Methods:36 cases were examined with CT,15 of them had MR imaging,34 cases were proved by experiment examination,and 2 cases by operation.Results:Multiple or single abnormalities were found in 36 cases,mainly located in white matter,also involved basal ganglion,cerebellum,and bum.Conclusion:CT/MR and contrast scan can provied important diagnosis information of acute disseminated encephalomyelitis,sometime,considering clinical situation of patients in order to distinguish it from infarction,tumor,toxic encephalopathy and multiple sclerosis.
