"The fistula usually occurs through the bladder dome (~ 60%). The posterior wall (~ 30%) and trigone (~ 10%) are less frequent sites 2. Colovesical fistulas and their causes can be characterised in several ways, although the fistulous tract itself is often difficult to demonstrate."

"On CT the fistula will be heralded by the presence of gas within the lumen of the bladder, or less frequently direct demonstration of the tract itself. Contrast may be instilled into the rectum 'on the table' before the acquisition of images to demonstrate a fistula."
"A contrast enema is most likely to show the actual fistula, although this still occurs in a minority of cases. The underlying cause will be demonstrated, with relevant findings to the diagnosis (e.g. diverticula, stenosing mass lesion, changes of Crohn's disease)."
