Abstract

A 72-year-old female experienced severe hyponatremia, leading to a serum sodium level of 102.5 mEq/L. Sodium levels were rapidly increased, resulting in osmotic demyelination syndrome (ODS). Magnetic resonance imaging is the most appropriate diagnostic tool for ODS, with the classic trident-shaped appearance formed by the hyperintense central pontine signal. Patients with ODS often require intensive supportive care and relowering of sodium levels.

摘要

一位 72 岁女性出现严重低钠血症，血清钠水平降至 102.5 mEq/L。钠水平迅速升高，导致渗透性脱髓鞘综合征（ODS）。磁共振成像（MRI）是 ODS 最适宜的诊断工具，具有由中央桥脑信号高信号形成的经典三叉形外观。ODS 患者通常需要强化支持治疗和降低钠水平。
