FIG 8. Otolaryngology referred this patient for imaging after palpating a mass in the "left parotid tail." Axial contrast-enhanced CT scan through the mass reveals a partly cystic mass in a typical location for a jugulodigastric lymph node (curved arrow). Normal parotid tail tissue is seen (straight white arrow). This was a metastatic node from a clinically occult primary squamous cell carcinoma, which is partly seen on this section in the left faucial tonsil (open arrow). Additional lymph nodes lower in the neck indicated a high-stage tumor. Upon chart review, the referring physician had noted mass effect in the left tonsil; however, a mucosal lesion was not present.
