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.”

<title>Abstract</title> Introduction: Integrin antagonist carbamate (IAC) – a newer αvβ3 integrin antagonist peptidomimetic molecule in the pipeline, has made the molecular imaging of tumour angiogenesis amenable. The study aims to investigate the biodistribution, clinical efficacy of 68Ga DOTAGA-IAC PET/CT in the detection of radioiodine refractory differentiated thyroid carcinoma (RAIR-DTC), to compare its diagnostic performance with the most commonly used imaging tool, 18F-FDG PET/CT. Materials and methods: Thi…
