Positron emission tomography/computed tomography upstages a T1 nasopharyngeal cancer patient from N0 to N1. A-D: PET/CT images reveal that in addition to the T1 nasopharyngeal primary, there is increased FDG uptake in a level II node which was 1.0 cm in size (arrows). FNA of this node confirmed metastatic carcinoma. Thus, the patient was upstaged as T1N1 and treated with concurrent chemotherapy with IMRT; E-H: The IMRT plan for this patient treated the right level II node to a dose of 70 Gy. IMRT: Intensity modulated radiation therapy; PET/CT: Positron emission tomography/computed tomography; FDG: Fluorodeoxygluocose.
