Breast cancer is the most frequent cancer and the leading cause of cancer-related death among females. Up to 30 percent of women with early-stage, non-metastatic breast cancer at diagnosis will develop distant metastatic disease. Renal metastasis from the breast cancer is a rare entity. We report a case of synchronized double primary breast cancer with isolated solitary metastatic to the kidney. Non-specific symptoms were occurred in routine surveillance after 4 years of initial diagnosis. 3-phase-CT and 18-F FDG PET-CT was performed subsequently. Left radical nephrectomy was performed. The histo-pathological diagnosis with immunohistochemistry was confirmed the metastasis from breast cancer. Breast cancer metastatic to the kidney may present a solitary renal mass, which mimics a primary renal tumour.
