Abstract
INTRODUCTION: Seizures are a common presenting complaint and account for approximately 1% of total emergency department (ED) visits. Seizures are especially common in children less than five years old as they have a lower seizure threshold as compared to adults. One potentially dangerous etiology that is far less common, especially in children, is thyroid storm, the extreme manifestation of hyperthyroidism. CASE REPORT: We describe the case of a 3-year-old girl who presented to the ED with an afebrile seizure but was found to be in thyroid storm. This case should serve as a reminder for emergency physicians to consider thyroid disease when evaluating patients presenting with seizures. CONCLUSION: Although most pediatric seizures are self-limited and frequently benign, it is imperative that the emergency physician evaluate for and rule out any potentially associated dangerous conditions such as thyroid storm.
