Preoperative fistulas are rare in patients with bladder mucosa-invading gynecological tumors. This is the first reported case of a vesico–vaginal fistula identified using 2-deoxy-2-[fluorine-18]fluoro-d-glucose positron emission tomography/computed tomography (18F-FDG-PET/CT) in a patient with vaginal cancer. A 61-year-old woman with vaginal cancer underwent 18F-FDG-PET/CT for assessment of the mass and lymph nodes. Assessment was difficult because overlap of FDG uptake occurred on 18F-FDG-PET/CT images obtained 60min after FDG injection. However, dynamic 18F-FDG-PET/CT clearly indicated the presence of a vaginal tumor–vesical fistula. This case illustrates the usefulness of dynamic 18F-FDG-PET/CT imaging when assessing a vesico–vaginal fistula.
