Benign sinonasal papilloma may be associated with intense FDG uptake on PET/CT. FDG PET/CT does not appear to reliably differentiate benign from malignant sinonasal papilloma.
18-Fluorine fluorodeoxyglucose positron emission tomography/computed tomography (PET/CT) has been shown to have use in the diagnosis of inflammatory and infectious diseases in addition to its primary use in cancer. We describe a case of early neurosyphilis that initially presented as symmetric, generalized lymphadenopathy on PET/CT. We conclude that PET/CT may play a role in evaluating targeted diagnostic interventions, disease extent, and treatment efficacy for disseminated syphilis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
