A 55-year-old man was diagnosed with squamous cell carcinoma in the middle thoracic esophagus. The FDG PET/CT revealed an incidental strong FDG-avid finding (SUVmax, 11) in the right parotid gland, which was subsequently confirmed as metastasis from the squamous cell carcinoma of esophagus via surgery. The current case adds another differential diagnosis of parotid FDG-avid lesion to the existing literature.
