The CT scan shows the following features:
- ovoid structure of fat-density in the left iliac fossa, adjacent to the sigmoid colon measuring (3.5 x 3.4 x 2 cm)
- thin peripheral high-density rim "hyperattenuating ring sign"
- no significant thickening of the adjacent colonic wall
- surrounding inflammatory fat stranding with thickening of the adjacent peritoneum
- central hyperdense dot is noted, representing most likely the thrombosed vascular pedicle
Hiatus hernia is noted.
