Uterine papillary serous carcinoma (UPSC) is a rare endometrial neoplasm with high mortality rates. While the malignancy has often metastasized to distant organs by the time of diagnosis, brain lesions are extremely rare and most commonly only observed in widely disseminated disease. Here, we present an unusual case of UPSC with brain metastasis discovered six years after undergoing treatment for stage IIIA disease. Compared to the few previous cases of brain metastasis from UPSC, this lesion exhibited unusual imaging characteristics. We also highlight a potential imaging interpretation pitfall which was associated with this case.
