| Summary: | Abstract
Fluorodeoxyglucose positron emission tomography (18FDG-PET) scan has become a valuable resource in the staging of lung cancer. Inflammation is known to cause false positives on 18FDG-PET scan. In the absence of symptoms suggesting a diagnosis of an inflammatory condition, 18FDG-avid lung masses on PET/CT scan is strongly suggestive of a diagnosis of lung cancer, rather than an inflammatory condition. We report the case of a 57-year-old man, with a history of heavy smoking and working in the sandblasting industry, with two suspicious 18FDG-avid nodules in the left lung. Surgical specimens of these nodules revealed findings suspecting giant cell arteritis rather than malignancy. |
