摘　　要：目的分析获得性肝性脑部变性(AHCD)的脑部MR表现,总结其特征性。资料与方法对23例获得性肝性脑部变性患者的脑部病灶信号特征及发病部位进行分析。结果获得性肝性脑部变性患者的脑部异常主要表现为双侧苍白球(20/23)、大脑脚(17/23)、中脑红核周围(17/23)、垂体前叶(3/23)等部位TIWI呈对称的高信号,T2WI未见异常信号。结论 T1WI上苍白球、大脑脚、中脑红核周围等部位出现的对称性高信号是获得性肝性脑部变性的较为特征性的征象。Objective To study and analysis the cerebral MRI finds of acquired hepatocerebral degeneration（AHCD） and summarize their characteristics. Materials and Methods Studied the signal characteristics and the diseased parts of the brain lesions in the 23 patients with AHCD. Results The cerebral abnormal MRI finds of AHCD mainly showed symmetrical high signal on T1WI in the glabus pallidus （20/23）, cerebral peduncle （17/23）, midbrain surrouding red nucleus（17/23）, and in the anterior pituitary（3/23） While T2WI demonstraied no corresponding alteration in signal intensity. Conclusion The typical MRI findngs of AHCD were symmetrical hyperintense on T1WI, primarily in the glabus pallidus, cerebral peduncle and midbrain surrouding red nucleus.
