Breast cancer rarely metastasizes to the uterus. In particular, lobular carcinoma of the breast more commonly spreads to the uterus when compared to invasive ductal carcinoma. PET-CT can be a tool to differentiate between fibroids and metastasis based on the maximum standardized uptake value (SUVmax). The authors report the case of a 37-year-old female with invasive ductal carcinoma (IDC) having significantly fluorodeoxyglucose (FDG)-avid masses on PET-CT which were later found to be metastases.
