目的：探讨热射病患者的脑部MRI表现。材料与方法选取8例经临床诊断为热射病的患者，均于发病后2～5d内行颅脑磁共振检查，检查序列包括T1WI、T2WI、T2-FLAIR、DWI、SWI；其中5例患者并进行了2～4次的随访MRI检查。结果8例热射病患者中5例可检出异常信号，部位包括脑干、小脑齿状核、小脑脚、小脑半球、海马、放射冠、半卵圆中心及右额颞顶叶，病灶性质包括微出血、细胞毒性水肿、血管源性水肿、出血性梗死、脑炎，小脑病变呈对称性分布。结论热射病可引发脑组织缺血、出血、梗死、炎症等多种性质病变，MRI表现具有一定特征性，常出现小脑的异常且呈对称性分布。

Objective: To investigate the MR findings of brain after heat stroke. Materials and Methods:Eight cases of patients diagnosed heat stroke by clinical methords were selected. The MR studies including T1WI, T2WI, T2-FLAIR, DWI, SWI were performed for 2-5 days after heat stroke. Five patients were followed up by the same MR studies with 2-4 times. Results:Among eight cases with heat stroke, five patients were detected abnormal signals which located at brain stem, cerebellar dentate nucleus, cerebellum feet, cerebellum, hippocampus, corona radiate, semi oval center and right frontal-temporal-parietal lobe. The lesions including micro hemorrhage, cytotoxic edema, vasogenic edema, hemorrhagic infarction, encephalitis. Symmetrical distribution were displayed for cerebellar lesions. Conclusions: Heat stroke can cause cerebral lesions such as ischemia, hemorrhage, infarction and inflammation. MR findings have certain characteristics which often involved in the cerebellum symmetrically.
