A 13-year-old Hispanic girl presented with a mass in the left side of her neck that had gradually developed over a 5-month period after an upper respiratory tract infection. Physical examination revealed that the left supraclavicular mass, which measured approximately 2 × 2 cm, was well marginated, not adherent to the skin, mobile over the underlying structures, painless, nonpulsatile, and firm and did not blanch with direct pressure. Magnetic resonance imaging of the mass demonstrated a low T1 signal, a high T2 signal, and intense uniform enhancement. A short tau inversion recovery sequence obtained in the coronal plane showed an increased signal (Figure 1, arrow). The mass was completely excised.
