Patient Data
Age: 65 years
Gender: Male
Note: This case has been tagged as "legacy" as it no longer meets image preparation and/or other case publication guidelines.
From the case:
Superior mediastinal mass - multinodular goiter
Frontal

Widening of the superior mediastinal contours, which extend superior to the thoracic outlet. Tracheal deviation to the left at the level of the thoracic outlet. This is suspicious for a thyroid mass with retrosternal extension.
From the case:
Superior mediastinal mass - multinodular goiter
Coronal non-contrast

CT confirms superior mediastinal mass secondary to multinodular goiter with retrosternal extension.
Case Discussion
In this case the multinodular goiter is so enlarged, it extends into the superior mediastinum, resulting in the cervicothoracic sign.
