Abstract: 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 ( <superscript>18</superscript> F-FDG-PET/CT) in a patient with vaginal cancer. A 61-year-old woman with vaginal cancer underwent <superscript>18</superscript> F-FDG-PET/CT for assessment of the mass and lymph nodes. Assessment was difficult because overlap of FDG uptake occurred on <superscript>18</superscript> F-FDG-PET/CT images obtained 60min after FDG injection. However, dynamic <superscript>18</superscript> F-FDG-PET/CT clearly indicated the presence of a vaginal tumor-vesical fistula. This case illustrates the usefulness of dynamic <superscript>18</superscript> F-FDG-PET/CT imaging when assessing a vesico-vaginal fistula.<br /> (Copyright © 2017 The Authors.
