Superior vena cava syndrome caused by a benign retrosternal multinodular goiter

Abstract

Retrosternal thyroid accounts for a significant percentage of anterior mediastinal masses, but has been described very rarely as the cause of superior vena cava (SVC) syndrome. Most cases of SVC syndrome occur as a complication of malignancy. The authors report the case of a patient with few respiratory symptoms, mild upper airway obstruction, and SVC syndrome caused by a benign retrosternal multinodular goiter.
