摘要
目的探讨高血压脑病(HE)的CT和MRI特点。方法回顾性分析65例临床诊断为HE患者的影像学资料,其中38例接受CT检查,5例接受MR检查,22例同时接受CT和MR检查。结果20例患者未发现异常;45例患者发现异常,其中26例表现为典型的顶枕部水肿,19例为弥漫性水肿。结论HE患者的头部CT、MRI可表现为无明显异常改变或典型的顶枕叶水肿及弥漫性脑水肿。CT、MR头部扫描及定期复查对HE的诊断和疗效评价具有重要意义。
Objective To investigate CT and MRI features of patients with hypertensive encephalopathy （HE）. Methods CT and MR images of 65 patients with HE were reviewed retrospectively. Among 65 patients, 38 underwent CT scan, 5 underwent MR scan and 22 underwent both CT and MR scan. Results No obvious changes were detected in 20 patients, while abnormal findings in the cranial CT and MRI were found in 45 patients, including typical edema in the parietal and occipital lobes （n=26） and diffuse edema of the brain （n=19）. Conclusion Cranial CT and MRI features of patients with HE can display with no obvious changes, typical edema in the parietal and occipital lobes or diffuse edema of the brain. Cranial CT and MR scan has great significance for the diagnosis and differential diagnosis of HE as well as the assessment of therapeutic effect.
