Contrast enhanced computed tomography of a patient with cT3 tongue squamous cell carcinoma on the left side showed a prominent suspicious left submandibular lymph node (large arrow). In addition, smaller rounded lymph nodes were evident bilaterally (small arrows). In spite of radiological findings, metastatic lymph nodes were not detected in postoperative histopathological examination after the elective neck dissection. A prominent thyroid was diagnosed as an incidental finding.
