A 73-year-old female patient with no relevant past medical history presented with post-menopausal vaginal bleeding. The patient underwent a hysteroscopy with endometrial biopsy revealing a poorly differentiated endometrial serous carcinoma. MRI staging depicted para-aortic lymph nodes and peritoneal metastases in the left upper quadrant. There were no signs of invasion of the outer half of the myometrium. Two polypoid lesions were identified in the posterior wall of the bladder and a confirmatory cystoscopy was recommended. Those lesions were later confirmed to be metastases of endometrial origin. Non-contiguous metastases to mucosal urinary bladder from endometrial carcinoma can occur and, as depicted in our case, can be well identified with magnetic resonance imaging.
