目的 研究慢性肝性脑脊髓病在头部 MRI上的特点。方法 本组观察 2 1例慢性肝性脑脊髓病病人 ,全部病人均符合慢性肝性脑病和慢性肝性脊髓病的诊断 ;并且均做头部 MRI、肝功能和血氨等检查。结果 2 1例头部 MRI显示有苍白球 T1 W1 高信号改变 ,这种异常信号可以随肝脏功能变化和肝性脑病的改善而改善 ,与血氨的浓度变化无关。结论 慢性肝性脑病病人头部 MRI显示苍白球 T1 W1 高信号 ,其发生与长期肝硬变及门脉分流导致肝的代谢异常有关。
Objective To study the characteristics of chronic hepatic encephalomyopathy (MRI) on head MRI. Methods 21 cases of chronic hepatic encephalomyelitis patients observed in this group, all patients are in line with chronic hepatic encephalopathy and chronic hepatic myelopathy diagnosis; and do head MRI, liver function and blood ammonia and other tests. Results 21 cases of head MRI showed hyperintense T1WI of globus pallidus. The abnormal signal could be improved with the improvement of hepatic function and hepatic encephalopathy, but not with the change of blood ammonia concentration. Conclusion MRI of the head of patients with chronic hepatic encephalopathy showed a hyperintense signal of T1W1 in the globus pallidus. The occurrence of T1WI was related to long-term cirrhosis and portal dysfunction.
