Key result
Focal hypermetabolic mediastinal brown fat was identified on PET/CT in 1.8% of oncologic patients, representing a potential pitfall that can mimic malignancy.

What is the prevalence, location, and appearance of hypermetabolic mediastinal brown fat on PET/CT in oncologic patients?
Hypermetabolic brown fat can localize to the mediastinum and mimic malignancy on FDG PET/CT, highlighting the importance of precise localization with fusion imaging to prevent misinterpretation.
Truong et al. (2004) conducted an observational in Oncologic patients (n=845). PET/CT was evaluated on Prevalence of focal hypermetabolic mediastinal brown fat. Focal hypermetabolic mediastinal brown fat was identified on PET/CT in 1.8% of oncologic patients, representing a potential pitfall that can mimic malignancy.
