Radiograph: Nonspecific diffuse thickening of the pre-cervical soft tissues as well as the aryepiglottic folds with protrusion into the tracheal air column. Relatively normal appearing epiglottis and tongue base. Increased prominence to the anterior neck soft tissues. There is no radio dense foreign body.
CT: Large peripherally enhancing multiloculated deep left neck collection measuring approximately 3.2 (AP) x 3.4 cm (TRV) x 5.0 cm (CC), with significant mass effect and medial displacement of the airway. The airway at the levels of the aryepiglottic folds (narrowest portion) is moderately stenotic.
