Thyrotoxic periodic paralysis: a case report and literature review

We describe a 19-year-old girl with a 3-month history of episodic muscular weakness, involving mainly lower limbs. Hypokalemia was documented in one episode and managed with intravenous potassium chloride. Hyperthyroidism was diagnosed 3 months after onset of attacks because of the mild symptoms. The patient was subsequently diagnosed as having thyrotoxic periodic paralysis associated with Graves' disease. Treatment with propranolol and methimazol was initiated and one year later underwent near total thyroidectomy
