Hypokalemia is one of the most frequent electrolytic disturbances encountered in clinical practice. It usually presents with symmetrical generalized muscle weakness and, on occasions, with arrhythmias. There are scarce reports of cases presenting with asymmetric or focal weakness in the literature and no systematic reviews on the subject. Therefore, our aim is to describe 2 cases of hypokalemic paralysis that presented as monoparesis and to review the literature on focal hypokalemic paralysis. Hypokalemic paralysis is usually reversible. However, it can be fatal if the diagnosis and treatment are delayed. It is important to take into account this presentation because failure to recognize it could lead to misdiagnosis, delaying the adequate treatment.
低钾血症是临床实践中最常见的电解质紊乱之一。它通常表现为对称性全身肌无力，有时还伴有心律失常。文献中鲜有关于不对称或局灶性肌无力病例的报道，也没有关于该主题的系统综述。因此，我们的目的是描述2例表现为单瘫的低钾性麻痹病例，并回顾局灶性低钾性麻痹的相关文献。低钾性麻痹通常是可逆的。然而，如果诊断和治疗延迟，可能会致命。考虑到这种表现很重要，因为未能识别它可能导致误诊，延误适当的治疗。
