Chest pain and paralysis after pulse prednisolone therapy an unusual case presentation of thyrotoxic periodic paralysis: a case report

Thyrotoxic periodic paralysis is a disease characterized by recurrent episodes of paralysis and hypokalemia during a thyrotoxic state. Thyrotoxic periodic paralysis is a common complication of hyperthyroidism in Asian populations, but can affect other ethnic groups as well. Due to population mobility, Thyrotoxic periodic paralysis is increasingly common in Western countries. Early diagnosis and prompt treatment of the thyrotoxic state and potassium supplementation prevent life-threatening complications associated with hypokalemia and muscle weakness. We present a young Turkish man who developed acute flaccid paralysis after receiving pulse prednisolone therapy for treatment of Pityriasis versicolor. His muscle strength and serum potassium fully recovered after potassium replacement and treatment of the thyrotoxic state which was a consequence of underlying Graves' disease.
