摘　　要：目的:探讨敌草快中毒性脑病CT和MRI影像表现。方法:于2021年5月,回顾性分析经临床确诊的10例敌草快中毒性脑病患者,分析其CT与MRI影像学特征。结果:10例患者均行CT检查,有8例同时行MR检查。10例中有7例患者在CT上有阳性征象,8例行MRI检查患者的影像上均有异常改变。CT主要表现为双侧小脑半球、桥脑、丘脑、基底节区对称性密度减低及脑组织不同程度肿胀。MRI主要表现为小脑半球、桥脑、丘脑、基底节区深部核团的对称性病变及脑组织水肿,T1WI低信号、T2WI及T2-FLAIR高信号改变,弥散加权成像(DWI)呈细胞毒性水肿。治疗后复查,CT与MRI均表现为病灶吸收,范围缩小。结论:敌草快中毒性脑病影像学表现具有一定特点,病变部位具有特征性,CT与MRI在敌草快中毒性脑病上有一定的诊断价值。Objective To explore the CT and MRI imaging findings of diquat toxic encephalopathy.Methods CT and MRI imaging features of 10 patients with diquat poisoning encephalopathy who had been clinically diagnosed were retrospectively reviewed.Results CT was performed in all 10 patients,and MRI was performed in 8 patients.In 10 patients,7 had positive signs on CT,and 8 patients with MRI examination had abnormal changes in the images.The main CT findings were symmetrical hypodensity in bilateral cerebellar hemisphere,brainstem,thalamus and basal ganglia,and swelling of brain tissue.The main MRI findings were symmetrical lesions and brain edema in the deep nuclei of cerebellar hemisphere,brainstem,thalamus and basal ganglia,low signal on T1WI,high signal on T2WI and T2-FLAIR,and cytotoxic edema on diffusion weighted imaging(DWI).On review after treatment,both CT and MRI showed resorption of the lesion,which narrowed in size.Conclusion The imaging findings of diquat poisoning encephalopathy are characteristic and the location of the lesion is characteristic,and CT and MRI have a certain diagnostic value in diquat poisoning encephalopathy,which is important for clinical treatment.
