Vitamin B12 deficiency causes haematological and neurological diseases. Subacute combined degeneration (SCD) of the spinal cord is characterized by degeneration of the posterior and lateral columns. We report two cases of SCD induced by nitrous oxide (N2O) anaesthesia. In both cases magnetic resonance imaging (MRI) of the spinal cord showed symmetric, reversible changes in the posterior columns, correlating well with patients' symptoms.
维生素B12缺乏会导致血液系统和神经系统疾病。脊髓亚急性联合变性（SCD）的特征是后柱和侧柱变性。我们报告了两例由氧化亚氮（N2O）麻醉引起的SCD病例。在这两例病例中，脊髓磁共振成像（MRI）均显示后柱有对称、可逆的变化，与患者症状密切相关。
