Abstract

We present a case of endometrioid carcinoma metastasis in the bladder mimicking as the second primary of urinary bladder on 18F-fluorodeoxyglucose positron-emission tomography/computed tomography (18F-FDG PET/CT). The presentations of bladder lesions on 18F-FDG PET/CT are varied, and rare presentations of common malignancies can pose a significant diagnostic challenge as in the index case and highlight the importance of histopathological examination to confirm any unusual FDG uptake confounding the diagnosis.
