摘　　要：目的探讨脑桥中央髓鞘溶解症(CPM)磁共振改变特点及其鉴别诊断。方法回顾性分析13例CPM病例,收集病史及临床表现,分析总结其磁共振改变特点及桥脑疾病的鉴别诊断。结果 13例CPM患者影像改变主要特点为,桥脑中央跨中线对称性T1WI低信号、T2WI高信号、T2FLAIR高信号、DWI高信号或等信号。主要常见病因为水、电解质紊乱,特别是低钠血症及其快速纠正,其它病因多见于慢性酒精中毒、重度营养不良及感染性、器官衰竭等。结论 CPM磁共振改变具有一定特点,但是需根据病史及临床表现进行相关疾病鉴别。Objective To investigate the change of magnetic resonance features and differential diagnosis of central pontine myelinolysis.Methods A retrospective analysis of 13 cases of CPM were collected from the medical records and clinical manifestations,and to summarize the change of magnetic resonance characteristics and pons disease. Results The main features of the image changes in 13 cases ofcentral pontine myelinolysis are as follows： the center of the central line of the symmetrical T1 WI has low signal,T2 WI has high signal,T2 FLAIR has high signal,and DWI has high signal or middle signal,etc. The main common disease causes are water and electrolyte disorders,especially low sodium and rapid correction of hyponatremia,and other causes are more common in chronic alcoholism,severe malnutrition and infection,organ failure and so on. Conclusion The change of central pontine myelinolysis magnetic resonance has certain characteristics,but it should be identified according to the history and clinical manifestations.
