Colovesical fistula in a patient with recurrent cervical cancer detected by FDG PET/CT.
We report the case of a 57-year-old woman with the history of stage IB cervical cancer. She was found to have a metastatic squamous cell carcinoma in sigmoid colon. FDG PET/CT was then performed for whole-body cancer work-up. Intense FDG activity accumulated in the sigmoid tumor, with an unusually high SUVmax of 72.42, and was seen downwardly connected with the activity of urinary bladder on PET images. On the coregistered CT images, irregular wall thickening was noted for both sigmoid colon and urinary bladder with a hypodensity tract communicating with each other. It was concluded that recurrent cervical cancer involving urinary bladder and sigmoid colon resulted in colovesical fistula.
