Abstract：
Hypokalaemic paralysis is a rare disorder characterized by rapid onset of symmetrical flaccid skeletal muscle weakness in the presence of reduced serum potassium levels. It is categorized as primary or secondary depending on the aetiology. Asymmetric or unilateral muscle weakness in hypokalaemic patients is a rare presentation. In patients with comorbid cardiovascular risk factors, this atypical manifestation can mimic acute stroke. Only a few of such cases have been reported in the literature. This report discusses the case of a 46-year-old hypertensive Ghanaian woman who presented to a District Hospital with sudden-onset right-sided flaccid weakness and a high blood pressure. Acute stroke was ruled out with computed tomography scan of the brain. Further laboratory evaluation demonstrated reduced serum potassium level, which was corrected with subsequent dramatic resolution of the muscle weakness.
摘要：
低钾性瘫痪是一种罕见的疾病，其特征是在血清钾水平降低的情况下迅速发作对称的弛缓性骨骼肌无力。根据病因将其分为原发性或继发性。低钾血症患者的不对称或单侧肌肉无力是罕见的表现。在患有心血管疾病危险因素的患者中，这种非典型表现可以模拟急性中风。文献中仅报道了少数此类病例。本报告讨论了一名46岁的加纳高血压妇女的病例，该妇女因突发性右侧弛缓无力和高血压而被送往地区医院。通过脑部计算机断层扫描排除了急性中风。进一步的实验室评估显示血清钾水平降低，随着肌肉无力的戏剧性解决，这一点得到了纠正。
