Myxedema coma and pituitary apoplexy are well-known life-threatening endocrine emergencies. The coincidence of these entities is exceedingly rare. Myxedema coma occurring as a result of pituitary lesion is a much less seen entity. A high index of suspicion is often required for early diagnosis as it is of particular importance in improving survival outcomes. We present a rare case of a patient with myxedema coma presenting as bradycardia and hypotension secondary to pituitary apoplexy, which was confirmed on magnetic resonance imaging (MRI). The patient was managed conservatively with levothyroxine and stress doses of steroid, with the resolution of hemodynamic changes and a decrease in the size of the suprasellar mass.
