摘要
目的强调脑桥外髓鞘溶解症(EPM)早期识别的重要性,了解EPM的影像学特点及治疗方法。方法回顾性分析1例急诊EPM患者的临床表现、影像学特点、诊疗过程,并复习相关文献。结果患者男性,因长期营养不良致严重低钠血症,补钠过程中出现EPM。头颅MRI检查示:两侧尾状核头及两侧壳核呈对称性等T_1稍长T_2信号,DWI呈稍高信号。两侧尾状核头部及两侧壳核对称性稍高信号,结合临床考虑脑桥外髓鞘溶解症。结论对于电解质紊乱,尤其低钠血症的患者补钠过程中需注意补钠速度,MRI对于EPM早期诊断具有较高价值。
Objective To emphasize the importance of early recognition of extramedullary myelinolysis(EPM)and to understand the imaging features and treatment of EPM.Methods The clinical manifestations,imaging features,diagnosis and treatment process of a patient with emergency EPM were retrospectively reviewed,and relevant literature was reviewed.Results In the male patients,severe hyponatremia caused by chronic malnutrition and EPM occurred during sodium supplementation.The MRI examination of the skull showed that the T1 slightly longer T2 signal was observed on both sides of the caudate nucleus and the nucleus of both sides,and the DWI showed a slightly higher signal.The symmetry of the caudate nucleus on both sides and the nucleus on both sides are slightly higher,combined with clinical consideration of extramedullary myelinolysis.Conclusion For electrolyte imbalance,especially in patients with hyponatremia,sodium supplementation rate should be paid attention to during sodium supplementation.MRI is of high value for early diagnosis of EPM.
