Thyroid storm is a rare but potentially fatal condition that is most frequently associated with Graves' disease. We present the case of a young woman who presented in thyroid storm, later diagnosed as being due to severe subacute thyroiditis. We discuss the diagnostic approach to thyroid storm, the initial management, and eventual treatment and course of subacute thyroiditis. This case illustrates the necessity to include subacute thyroiditis in the differential diagnosis of severe thyrotoxicosis and thyroid storm.
