Multiple sigmoid colonic diverticulae.

Thickened sigmoid colon with pericolic inflammatory change.

Case Discussion

One of the commoner causes of a colovesical fistula is complicated diverticular disease.

This case shows multiple signs to confirm the diagnosis:

1. Thickened adjacent colon with pericolonic inflammatory change

2. Diverticulae in the sigmoid colon

3. Large volume of air in the bladder ( without prior catheterisation or intervention )

4. Gas tracking across the colonic wall into the urinary bladder
