ABSTRACT
Pregnancy constitutes a significant factor for thyroid enlargement. However, acute respiratory failure as a result of airway obstruction from an enlarged thyroid gland is an unusual incident. The case presented here concerns a 27-year-old black woman in her 20th gestational week who underwent an urgent operation for removal of a nontoxic, multinodular, mildly substernal goiter that was causing severe upper airway obstruction leading to acute life-threatening respiratory failure. Diagnosis of an extrathoracic tracheal stenosis was based on spirometry with analysis of the flow volume curve and was confirmed by magnetic resonance imaging of the neck. Despite operational risks to the mother as well as the fetus during gestation, an urgent thyroidectomy was carried out successfully. The postoperative period progressed normally and the patient completed her pregnancy with no further respiratory symptoms.
