Widespread hypermetabolic lesions due to multicentric form of Castleman disease as the cause of fever of unknown origin revealed by FDG PET/CT
A 46-year-old male patient presented with fever for over 5 months. An FDG PET/CT was acquired to evaluate the source of the fever. The images showed many hypermetabolic foci throughout the imaged regions, which mainly corresponded to enlarged lymph nodes. Pathological examination demonstrated that the patient suffered from a multicentric form of Castleman disease.
