Figure 3 Axial pelvic CT with intravenous and oral contrast showing a large pelvic fluid collection with homogeneous low attenuation, consistent with inflammatory fluid or early abscess formation, causing mass effect on adjacent structuresPreoperative imaging is shown in Figure 3, demonstrating a large pelvic fluid collection consistent with an inflammatory process, most likely representing complicated free fluid or evolving abscess formation secondary to perforated appendicitis.
