[Superior vena cava syndrome caused by multinodular goiter].

Currently, the vena cava superior syndrome (VCSS) is mainly of oncologic origin. We report here four cases of this syndrome caused by intrathoracic multinodular goiter. All patients had compressive symptoms, particularly of the oesophagus and trachea. Axial CT was the imaging technique that delineated the intrathoracic multinodular goiter compressing brachiocephalic vessels. Surgery (total thyroidectomy) was used and all compressive symptoms resolved.
