A 74-YEAR-OLD MAN complained of an intermittently discharging sinus at the anterior border of the lower third of the left sternocleidomastoid muscle. The condition had been present since birth. He had no fever or other systemic complaints. Physical examination of the oral cavity and pharynx showed no fistulous opening. The fistulous tract was injected with a contrast medium (Figure 1). An axial computed tomographic scan of the neck is shown in Figure 2.
