摘　　要：目的分析10例急性超大面积大脑半球梗死患者影像学表现及临床特征,并复习相关文献。方法选取2014年8月—2017年9月徐州市丰县人民医院收治的急性超大面积大脑半球梗死患者10例,回顾性分析其影像学表现及临床特征。结果既往史:高血压9例,心房颤动6例,脑梗死5例,高脂血症5例,冠心病4例,糖尿病2例。临床表现:急性意识障碍、昏迷10例。首次CT检查呈现阴性征象者2例;呈现阳性征象者8例,其中患侧脑沟变浅或消失8例,大脑半球区域性稍低密度模糊影6例,右侧大脑中动脉高密度影3例。随访期间,10例患者影像学检查均显示梗死灶最大累及患侧大脑半球85%~98%、恶性水肿加重、占位及脑疝征象,3例患者T2加权(T2WI)图像示右侧颈内动脉高信号征,3例患者CT图像示梗死灶少许出血。1例患者行大骨瓣切除减压术治疗,9例患者采用常规保守治疗。随访3 d^4周,10例患者均死亡。结论急性超大面积大脑半球梗死患者临床表现危重,预后极差,CT及磁共振成像(MRI)可明确诊断。Objective To analyze the imaging findings and clinical features of10patients with acute ultra-large area cerebral hemispheric infarction,and review the related literatures.Methods From August2014to September2017,a total of10patients with acute ultra-large area cerebral hemispheric infarction were selected in the People's Hospital of Fengxian,Xuzhou,and the imaging findings and clinical features were retrospectively analyzed.Results Past medical history:9cases showed hypertension,6cases with atrial fibrillation,5cases with cerebral infarction,5cases with hyperlipidaemia,4cases with coronary heart disease,2cases with diabetes.Clinical features:all of the10patients performed as acute disturbance of consciousness and coma.The first CT examination results:2cases with negative signs;8cases with positive signs,thereinto8cases showed shallow or disappeared gyri in the affected side,6cases showed cerebral hemispheric slightly low-density fuzzy shadows,3cases with high-density shadows in the right middle cerebral artery.Imaging findings during the follow-up:all of the10patients showed infarction focus involved85%-98%cerebral hemisphere in the affected side,exacerbation of malignant edema,occupation lesions and cerebral hernia,besides,3cases showed increased signal intensity in the right internal carotid artery,3cases'CT imagings showed a little bleeding in the infarction focus.Therapeutic methods:1case received large-bone flap resection decompression,9cases received routine conservative treatment.During the follow up(3days to4weeks),all of the10patients died.Conclusion Acute ultra-large area cerebral hemispheric infarction is dangerous with severe clinical manifestations and poor tewifically prognosis,CT and MRI can confirm the diagnosis.
