TITLE: Abdominal Abscess
Multiplanar reformat image in the coronal plane demonstrates the left lower quadrant abdominal abscess. An air-fluid level is present within a well-circumscribed fluid collection with an enhancing wall. This collection is adjacent to and contiguous with a thickened descending colon, with adjacent inflammatory fat stranding. Note the diverticula in the ascending and region of the sigmoid colon.
