Description

The patient was a 58-year-old man who had complained of a right neck mass. During maintenance dialysis, a biopsy was scheduled for right-neck lymphadenopathy in our hospital, but tumorous lesions were observed in the right palate tonsil. DWIBS was performed, and the imaging suggested cervical lymph node metastasis of oropharyngeal carcinoma. The results of the palate tonsil biopsy were p16 positive squamous cell carcinoma. Oropharyngeal carcinoma (T2N1M0) was cured by radical radiotherapy. One year after treatment, there has been no recurrence. DWIBS was an excellent medical and economical hospitalization modality compared to PET-CT. In addition, there is no contrast agent or radiation exposure, it is not affected by diabetes, and it imposes little burden on patients.
