Patient Data

Age: 71
Gender: Male
Modality: CT

CT abdomen

Thickened apex to the sigmoid loop just prior to the take-off of the descending colon, containing multiple diverticulae. Adjacent to this is a 10 cm fluid-gas containing collection with surrounding inflammatory change.

No free gas in the upper abdomen.

Tiny simple cyst in the liver. Solid organs otherwise normal.

The surgical notes from the laparotomy concur with the CT findings.

Case Discussion

The typical appearances of a colonic diverticular perforation with a large resultant abscess/inflammatory mass.

The spectrum of acute diverticular disease can range from a single inflamed diverticulum, through to a inflamed colonic segment, sealed off localized perforation and larger perforation with or without a collection.
