Radiological insights into diverticulitis: Clinical manifestations, complications, and differential diagnosis

Figure 9 Colo-vesical fistula secondary to sigmoid colon diverticulitis. A young male patient with fecaluria and pneumaturia. A: Coronal contrast-enhanced computed tomography image demonstrated findings consistent with sigmoid diverticulitis. Loss of fat planes between the sigmoid colon (blue arrows), an air-filled tract extending from the sigmoid colon to the bladder lumen, indicative of a colo-vesical fistula (yellow arrows), and the adjacent bladder segment with bladder wall thickening in the affected area was visualized; B: The presence of intraluminal air within the bladder was noted (orange asterisks).
