Diverticulitis: Pelvic Abscess with Fistulae

Findings
There is a large gas containing pelvic abscess with adjacent tiny collections of air and contrast in fistulous tracts.

Discussion
CT stages diverticulitis from Stage 0 through Stage IV depending on surrounding involvement and severity. Stage 0 shows only minor local colonic wall involvement and may be treated conservatively with antibiotics. The other stages usually necessitate surgical intervention. Stages I and II show contiguous spread of inflammation outside of the colon. Stages III and IV show peritoneal involvement with distant abscesses, ascites, through to frank peritonitis.
