A 46-YEAR-OLD woman presented to the emergency department with a slowly enlarging neck mass that extended to the upper part of her chest (Figure 1). She had been aware of the mass for several months, but denied any constitutional symptoms. The rest of her medical history was noncontributory. A physical examination revealed an 8 × 10-cm firm, nontender, nonmobile, midline neck mass, extending from the lower border of the cricoid cartilage to the upper sternum. The findings of the rest of the examination, including an indirect laryngoscopy, were normal. The computed tomographic findings are shown in Figure 2 and Figure 3.
