FIG 4. Earring lesion of the parotid tail. Axial contrast-enhanced CT scan shows typical appearance of a cystic Warthin tumor. Note the nodule of soft tissue (straight white arrow), which is commonly seen. A small amount of parotid tissue (open arrow) is seen anterior to the mass. Note parotid tail anatomic landmarks: SCM posteriorly and platysma (curved white arrow) laterally. (Reprinted with permission from reference 1.)
