Myxedema Coma: Recognition of a Rare Endocrine Emergency.

ABSTRACT

An 82-year-old patient with multiple comorbidities presented to the emergency department with progressive dyspnea, orthopnea, and anorexia. Despite initial treatment for community-acquired pneumonia and decompensated heart failure, her condition deteriorated, manifesting as severe hypotension, bradycardia, and refractory hypothermia. A detailed medical history and extensive systematic investigation led to the documentation of hypothyroidism complicated by myxedema coma, in the context of chronic amiodarone use and precipitated by sepsis. Treatment with intravenous levothyroxine and glucocorticoids resulted in significant clinical improvement, leading to eventual hospital discharge. This case highlights the complexity and diagnostic challenges of myxedema coma, emphasizing the importance of early recognition, appropriate application of diagnostic scoring systems, and describing key aspects of the proper management of this rare endocrine emergency, whose symptoms and clinical signs are nonspecific.
