Not just gastroenteritis: thyroid storm unmasked.

Establishing the diagnosis of thyroid storm is difficult in the ED, especially where there is no antecedent history of thyroid disease or clinical clues like goitre, exophthalmos or altered mentation, yet early recognition and treatment are essential in reducing mortality and morbidity from this endocrine emergency. We present a case where suspected infective gastroenteritis in a newly diagnosed diabetic masked the major symptomatology of thyroid storm, and review the diagnosis and management of thyrotoxic crisis.
