Abstract

45 years old diabetic male underwent an intensive work up for fever and body aches for three months. Extensive battery of laboratory work up revealed him to have a high ESR with a normal CRP, a CT thorax finding of mediastinal lymphadenopathy along with apical pleural thickening. On the basis of these clues he was given ATT without much benefit. He was then referred for PET Scan which showed symmetrical FDG uptake in both tibiae as well as femora; a rare finding leading to bone marrow biopsy from tibia and in turn a final diagnosis and a definitive treatment.

Key words: Fever of Known Origin, FDG PET/CT, Infection
