Fig. 1. Images of preoperative CT showing multiple neck lymph node metastases. Contrast-enhanced CT images showing multiple hyper-enhancing lymph nodes in the left retropharyngeal space and left neck at level 2 (A), level 3 (B), and level 4 (C). On contrast-enhanced CT images obtained one year after surgery, enlarged, enhancing lymph nodes remain in the left retropharyngeal space and left neck level 2 (D). The sizes of the residual contrast-enhancing lymph nodes did not significantly change during the follow-up period. Fig. 1. Images of preoperative CT showing multiple neck lymph node metastases.
