An adolescent male with no clinically significant medical history presented with a left-sided, anterior neck mass. His only subjective complaint was a feeling of neck “tightness.” Neck examination revealed a left-sided 2 × 3-cm firm, nonmobile, nonerythematous, nontender mass lateral to the cricothyroid membrane extending to the thoracic outlet that did not move with tongue protrusion.
Ultrasonography (US) was performed. A transverse image of the thyroid gland (Figure, A) showed ill-defined hypoechoic areas in the left lobe, suggesting edema and phlegmonous change. A focal hypoechoic area in the medial aspect may represent abscess or necrosis. The overlying soft tissues were diffusely edematous.
