A 65 year-old diabetic man with LLQ pain and lose stool for weeks.
Ultrasound detected some diverticula 7-9mm and a mass of sigmoid colon leading to an colo-colonic intussussception ?.
Colonoscopy noted some sigmoid diveticula and a tumor caused narrowing 70% the lumen of the sigmoid colon.
MSCT confirmed an abscess of sigmoid colon maybe from an acute inflammation.
Surgery removed the sigmoid colon which had some diverticuls and a perforated diverticulum. It existed no tumoral mass of the sigmoid colon.
Microscopic result was an acute sigmoid colitis having diverticula with a perforated abscess of a diverticulum.
Complicated diverticulitis : perforation, abscess are still rare conditions for MSCT and abdominal ultrasound (POCUS).
