Presentation
Lower abdominal pain, sent by the urologist to rule out urinary stone
Patient Data
Left lateral urinary bladder wall 4.6 cm long transmural focal thickening secondary to active diverticulitis of sigmoid colon. Dirty fluid fat planes between bladder and inflamed diverticuli, though no evident fistulation.
Case Discussion
This study shows active sigmoid diverticulitis and secondary inflammation of left lateral urinary bladder wall. The absence of any air fluid level within the urinary bladder is an indirect evidence of absence of any colovesical fistulation. Administration of either a rectal enema or acquiring images in urographic phase will better delineate, though more often than not, a plain study suffices in reaching the diagnosis.
