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.
低钾性麻痹是一种罕见的疾病,其特征是在血清钾水平降低的情况下,迅速出现对称性弛缓性骨骼肌无力。根据病因,它可分为原发性或继发性。低钾血症患者出现不对称或单侧肌肉无力的情况较为罕见。对于合并心血管危险因素的患者,这种非典型表现可能会被误诊为急性中风。文献中仅报道了少数此类病例。本报告讨论了一名46岁的加纳高血压女性患者的病例,该患者因突发右侧弛缓性无力和高血压就诊于一家地区医院。脑部计算机断层扫描排除了急性中风。进一步的实验室检查显示血清钾水平降低,随后肌肉无力症状戏剧性地得到缓解。
