Contrast-enhanced abdominal CT shows some inflammatory stranding in the fatty tissue adjacent to the descendo-sigmoid junction, with demarcation of a small, fatty ovoid structure showing a hyperattenuating rim, representing an inflamed and/or ischaemic epiploic appendage. There is no diverticulitis, abscess, or perforation.
Incidental findings include sigmoid diverticula without acute inflammatory changes, an incidentaloma of the left adrenal gland, several liver haemangiomas, small renal cysts, and a small hiatus hernia.
