CTICasesMultinodular Goiter
Imaging findings
Lateral chest radiograph and CT show a massive, lobulated, and heterogeneous thyroid mass extending from the neck into the middle mediastinum, causing severe anterior and rightward displacement and compression of the trachea. Physical exam described football-sized masses in the neck.
Key takeaways
Intrathoracic multinodular goiters are benign thyroid enlargements that commonly descend into the chest. Although often taught to locate in the anterior mediastinum, goiters frequently track along the pretracheal fascia into the middle mediastinum, presenting as retrotracheal or paratracheal masses that cause tracheal narrowing and symptoms of dyspnea or dysphagia, requiring surgical resection.
