A 65-year-old patient diagnosed with 4 + 3 PCa underwent radiation, hormonal and chemotherapy and became hormone refractive. On referral, PET imaging revealed bone lesions on maximum intensity projection of fluoride PET (a) and PSMA PET (b). The majority of bone lesions were sclerotic in nature having high intensity uptake on fluoride PET (a) but reduced uptake on PSMA PET (b). Fused transaxial PET/CT images showing two sclerotic rib lesions on fluoride PET (c), whereas PSMA PET showed only one sclerotic lesion (d, left arrow over rib). Respective sclerotic lesions showed on axial CT (e)
