18F-PSMA 1007 Uptake in a Man With Metastatic Breast Cancer

Abstract A 72-year-old man, who is known with a case of metastatic carcinoma of the breast, was referred for 18 F-PMSA 1007 PET/CT with clinical suspicion of synchronous prostate cancer. 18 F-PSMA 1007 PET/CT scan detected no abnormal tracer concentrating lesion in the prostate gland; however, abnormal tracer concentration was noted in soft tissue lesions in left breast, metastatic lymph nodes, and skeletal lesions. Compared with 18 F-FDG PET/CT, more bone lesions were detected on 18 F-PSMA 1007 imaging. The findings of our case open the possibility of imaging metastatic breast cancer with 18 F-PSMA 1007 in men.
