Circumferential wall thickening and luminal narrowing through a significant length of the sigmoid colon with extensive pericolonic fat stranding. Extra luminal collection containing fluid and gas measuring 21 x 25 mm is seen in the left iliac fossa inferior to the inflamed segment of sigmoid colon. There are additional scattered locules of free gas elsewhere in the abdomen, including under the left hemidiapragm. Appearances are in keeping with perforated sigmoid diverticulitis.
Circumscribed 25 x 24 mm hypoattenuation focus with peripheral calcific foci in the right adnexae is compatible with a complex ovarian cyst and this needs to be further evaluated with a dedicated pelvic ultrasound.
Thickened, inflamed segment of sigmoid colon with small local collection containing fluid and gas, as well as trace to small volume pneumoperitoneum. Appearance is most consistent with sigmoid diverticulitis complicated by perforation.
