Nucl. Med. Technol.2024 Jun 01; 52 AB - 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.
