title: Multiple Pathologies Seen on a Single Contrast-Enhanced 18F-FDG PET/CT: Reiteration of Lessons Previously Learned.
abstract: We here present the staging contrast-enhanced F-FDG PET/CT images of a 53-year-old woman with right breast cancer. Apart from the F-FDG avid primary breast tumor, F-FDG avid thyroiditis, F-FDG avid right paratracheal tubercular lymphadenitis, and non-F-FDG avid pancreatic neuroendocrine tumor were seen on PET/CT. All the lesions were confirmed with fine-needle aspiration cytology. This interesting case demonstrates a spectrum of true-positive, false-positive, and false-negative lesions on a single F-FDG PET/CT examination.
