Abstract

We present the case of a young woman with Hodgkin lymphoma exhibiting physiologic ¹⁸F-FDG uptake in brown adipose tissue and lactating breast on consecutive ¹⁸F-FDG PET/CT scans. Both entities are common imaging interpretation pitfalls and should be recognized in oncologic ¹⁸F-FDG PET/CT practice. We review the imaging features and differential diagnosis of these 2 entities and discuss the radiation safety precautions during breastfeeding.

Keywords: FDG; PET; breast; brown adipose tissue; lactating.
