摘要

运动无力患者的鉴别诊断范围很广，急诊科在评估其根本原因时需要采取系统的方法。虽然一氧化二氮神经中毒并不常见，但对于有过接触的患者来说，将其作为可能的鉴别诊断是非常重要的，因为治疗方法是现成的。我们报告了一例因一氧化二氮引起维生素 B12 缺乏而导致脊髓亚急性合并变性的磁共振成像病例。

Nitrous oxide-induced subacute combined degeneration of the spinal cord

The differential diagnoses of a patient presenting with motor weakness is broad and requires a systematic approach at the Emergency Department when evaluating its underlying cause. While nitrous oxide neurotoxicity is uncommon, it is important to consider it as a possible differential in patients with preceding exposure, as treatment is readily available. We present a case report with magnetic resonance imaging images of subacute combined degeneration of the spinal cord due to nitrous oxide induced vitamin B12 deficiency.
