Figure 1

A 65-year-old male patient affected by pharyngeal cancer with lymph nodal relapse (secondary disease relapse: the first relapse in the neck lymph nodes had been treated with surgery and radiotherapy one year before). (a) Axial, contrast-enhanced, full-dose CT shows a small lymph node, which seems to infiltrate the upper esophagus. (b) As evident from contrast-enhanced PET/CT fused images, this lymph node does not display increased FDG uptake. Subsequent endoesophageal ultrasound biopsy confirmed the presence of lymph node metastasis. The patient was then submitted to chemotherapy. CT, computed tomography; PET, positron emission tomography; FDG, [18 F] fluorodeoxyglucose.
