Diverticulosis

Diverticulosis means the colon has small outpouchings called diverticula. It is common, especially with age, and may be found incidentally on CT. The word diverticulosis alone does not mean infection or inflammation.

Also seen as: colonic diverticulosis, diverticular disease.

Diverticulosis is a very common age-related abdominal finding.

• Age-related structural change in the colon wall
• Chronic pressure-related change
• Dietary and bowel habit factors
• Background diverticular disease without active inflammation

• The report describes diverticulitis, abscess, perforation, or surrounding inflammation
• There is fever or focal lower abdominal tenderness
• Symptoms and labs suggest active infection or complication

• Diverticulosis alone usually needs no imaging follow-up
• Active diverticulitis is managed differently from incidental diverticulosis
• Doctors focus on whether inflammation is present

• Scattered colonic diverticulosis without diverticulitis.

• Sigmoid diverticulosis noted incidentally.
