Hypokalemic periodic paralysis is an uncommon complication of thyrotoxicosis, and very rare as a presenting symptom. It is most frequent in east Asian and Japanese males, but extremely rare in others. Only 1 case has previously been reported from Israel. We present a 29-year-old Arab man who presented with sudden paralysis of both legs. Physical examination revealed signs of thyrotoxicosis, and laboratory tests showed profound hypokalemia. Oral potassium resulted in rapid disappearance of symptoms, and after restoration of the euthyroid state, there were no further attacks. This case shows that thyrotoxic hypokalemic periodic paralysis is not confined to males of east Asian and Japanese origin, and that adequate treatment with oral potassium and antithyroid drugs is successful, and should be given as soon as possible.
低钾性周期性麻痹是甲状腺毒症的一种罕见并发症，作为首发症状极为罕见。它在东亚和日本男性中最为常见，但在其他人群中极为罕见。此前以色列仅报道过1例。我们报告1例29岁的阿拉伯男性，他突发双腿麻痹。体格检查发现甲状腺毒症体征，实验室检查显示严重低钾血症。口服钾后症状迅速消失，甲状腺功能恢复正常后未再发作。该病例表明，甲状腺毒症性低钾性周期性麻痹并不局限于东亚和日本男性，口服钾和抗甲状腺药物的充分治疗是成功的，应尽早给予。
