            Patient 66 year old, with history of right breast infiltrating carcinoma treated with surgery, Radiation Therapy and Chemotherapy 9 years ago. Since In recent months complains of progressive general body decline and skeletal pain. Other imaging studies: Mammography left: 5 mm nodule in upper external quadrant with the appearance of benign intramammary lymph node. Bone scan: diffuse bone involvement due to metastasis, irregular uptake in lung fields and liver, suggestive of secondary lesions. Chest CT: no pathological findings were found. FDG PET showed multiple foci of intense increased uptake  in axial skeleton, skull, proximal humerus and proximal femur. In the remainder of the study, there is normal distribution in brain, lungs, liver, spleen, colon, kidneys and bladder pyelocalicial systems. In conclusion, hypermetabolic activity in skeletum compatible with extensive bony metastases.

            Interestingly, no soft tissue organs had secondary involvement and the onset of these lesions was rather late after the early apparent disease and primary tumor control..
