Aim: to present a rare case report of the accidental urinary bladder carcinoma finding on 18F-FDG positron emission tomography/computed tomography (PET/CT) in a 62-year-old man with non-small cells lung cancer before treatment.

Method: The whole body PET/CT scan from base of skull to mid femur was obtained 60 minutes after intravenous injection of 18F-FDG (491 MBq - 5.4 MBq/kg). The PET scan acquisition time was 2.5 minutes per bed position and seven bed positions were necessary. Contrast-enhanced CT (venous phase) provided both full CT evaluation (including intravenous and oral contrast) and PET attenuation correction.

Results: The examination detected 18F-FDG PET/CT positive tumor in the left lung and left hilar and mediastinal metastatic lymphadenopathy and 18F-FDG positive, accidental tumor in the urinary bladder and left inguinal metastatic lymphadenopathy. The subsequent cystoscopy resection was performed and urinary bladder carcinoma was proven by histopathology.

Conclusion: 18F-FDG PET/CT imaging led to accidental detection of the urinary bladder carcinoma in the early stage and made subsequent successful cystoscopy resection treatment possible. The report gives notice for the accidental detection of the duplicate tumor during PET/CT imaging.
