A 75-year-old woman initially investigated with conventional contrast-enhanced MDCT during a bout of acute diverticulitis (a–c). Severe stratified mural thickening is observed throughout the entire sigmoid colon, with oedematous submucosa, diverticula, perivisceral fat inflammatory changes (*), and fascial fluid (thin arrows). Three weeks later, after conservative treatment, WE-MDCT with limited bowel preparation was performed to plan surgery, when endoscopy was still considered contraindicated. A significant decrease of sigmoid mural thickening and resolution of perivisceral acute inflammatory changes are observed (d–e), allowing limited laparoscopic sigmoid colon resection to be performed. Good distension of the upstream large bowel is achieved, without further abnormalities
