A 27-year-old man with known asthma presented to the emergency department with stridor and shortness of breath. His symptoms, which had begun 3 years earlier, had coincided with blunt trauma, but in the past 3 weeks, they had become progressively worse. There was a palpable, painless, nontender, soft mass in the left side of the neck. It moved with deglutition but not with tongue protusion. Computed tomography (CT) (Figure 1and Figure 2) demonstrated a large left paraglottic and supraglottic mass measuring 4.2 × 2.7 × 5.4 cm. The lesion was hypodense peripherally, with central areas of moderate contrast enhancement. It was well defined, bilobed, and separate from the thyroid gland, with no cartilage destruction.
