'bilateral Hot Forearm Sign': Ingeminating the Pattern of Physiological Uptake of 18F-Fludeoxyglucose

摘要

Exertion and exercise increase glucose metabolism within the skeletal muscles causing increased fludeoxyglucose (FDG) uptake on 18 F-FDG positron emission tomography/computed tomography (PET/CT). Here, we present findings of 18 F-FDG PET/CT in a patient with acute viral hepatitis A-induced liver failure with multiple foci of pyoderma and incessant itching resulting in increased FDG uptake in the muscles of the bilateral forearm, producing the 'bilateral hot forearm sign.' © 2024 Indian Journal of Nuclear Medicine.
