68 years old female patient presented with right breast lump biopsy revealed invasive duct carcinoma grade II (luminal A subtype). Axial CECT image (a) revealed a rather defined right breast soft tissue mass lesion measuring about 29 × 36 mm at lower inner quadrant that was eliciting increased tracer uptake reaching 5 SULpeak in axial PET (b) and fused PET/CT (c) images. On follow-up after completion of chemotherapy, morphologic and metabolic regression of the mass was noted in the form of reduction in size (reaching 9 × 16 mm) in axial CECT image (d) denoting partial response and reduction in SULpeak (reaching 2.1) in axial PET (e) and fused PET/CT (f) images denoting partial metabolic response
