Unilateral paralysis is an alarming symptom with broad differential diagnoses, including stroke, Todd's paralysis, myelopathy, and peripheral neuropathy. Hypokalemic paralysis (HP), a neuromuscular disorder associated with muscle dysfunction, is caused by hypokalemia and manifests as symmetric proximal extremity muscle weakness. Unilateral paralysis has rarely been reported in the literature. Once hypokalemia is corrected, HP is usually reversible. Delayed diagnosis and treatment may result in fatal consequences. Here, we report an atypical case of unilateral weakness along with a review of the literature on unilateral HP.
单侧瘫痪是一种令人警醒的症状，其鉴别诊断广泛，包括中风、Todd 瘫痪、脊髓病和周围神经病。低钾性瘫痪（HP）是一种与肌肉功能障碍相关的神经肌肉疾病，由低钾血症引起，表现为对称性近端肢体肌无力。单侧瘫痪在文献中很少见。一旦纠正低钾血症，HP 通常是可逆的。延迟诊断和治疗可能导致致命后果。在此，我们报告一例单侧肌无力的非典型病例，并对单侧 HP 的文献进行了回顾。
