FDG PET/CT in Monitoring Antituberculosis Therapy in Patient With Widespread Skeletal Tuberculosis.

FDG PET/CT imaging is a useful diagnostic tool in the evaluation of both neoplastic and inflammatory lesions and has a promising role in monitoring therapeutic response. We present a 50-year-old man whose initial PET/CT scan showed multiple foci of intense FDG activity in lytic lesions in the bones. A diagnosis of skeletal tuberculosis was confirmed after bone biopsy. Follow-up FDG PET/CT performed after 12 months of regular antituberculosis treatment demonstrated complete normalization of FDG activity in the bones.
