Differential Diagnosis of Warthin＇s Tumor Complicated with Lung Adenocarcinoma by 18F- FDG PET/CT Imaging and Radioisotope Scanning with Tc-99m Pertechnetate： A Case Report and Literature Review

摘要

A seventy eight years old male patient underwent a whole body 18F-FDG PET/CT imaging to diagnose the lesion which was showed in the right lung by a chest X ray test and CT scan before.Besides the intense 18F-FDG uptake of the lesion in the right lung,a lesion in the left parotid gland also showed intense 18F-FDG uptake.To evaluate the pathology of the lesion in the left parotid gland,a parotid gland scintigraphy imaging with Tc-99m pertechnetate was done and revealed a Warthin's tumor.Later a fine needle aspiration(FNA)confirmed that it was a Warthin's tumor.
