From: Successful management of trachea stenosis with massive substernal goiter via thacheobronchial stent
Magnetic resonance imaging (MRI) (A) and computed tomography (CT) (B) demonstrated a massive elliptical substernal goiter, displacing the trachea and adjacent large vessels to the patient’s right, contributing to severe intrathoracic tracheal compression up to 6 cm in length and the narrowest caliber of the trachea (arrows in light red) was about 3.0 mm in diameter.
