The radiograph shows some evidence of hyperinflated lungs, consistent with COPD. There is a small right effusion evident.
Of note is a superior mediastinal mass, which is causing right-sided and anterior displacement of the intrathoracic trachea. The differential includes possible adenopathy related to a carcinoma or a substernal goiter. Further diagnostic studies and surgical evaluation are warranted.
In this particular case, review of the patient’s imaging history showed he had a chest radiograph two years ago, at which time these findings were present. This favors substernal goiter as the diagnosis. Multinodular goiter was later confirmed with a thyroid ultrasound, and referral to general surgery was made.
