Abstract

We present the case of a 69-year-old female patient with no personal or family history of any thyroid disease, who attends with a convulsive state of sudden onset, right hemibody and sphincter relaxation, also associated with disorders of the state of consciousness, bradycardia, bradypnea and edema of difficult godet in lower limbs.

Complementary analyses showed respiratory acidosis, hyposecretion of T4 and elevation of the thyroid stimulating hormone by negative feedback. These results corroborated

the presumptive diagnosis of myxedema coma. The corresponding hormonal treatment with levothyroxine was undertaken, to which it responded satisfactorily and was discharged 24 days after admission, pending evaluation by the endocrinology specialist for an outpatient hormone replacement therapy.
