What condition is characterized by inflammation or localized perforation of diverticula with abscess formation?

Diverticulitis is the condition characterized by inflammation or localized perforation of diverticula, which are small pouches that can form in the wall of the colon. When these diverticula become inflamed or infected, it can lead to complications such as abscess formation. This inflammation occurs due to factors like stagnant stool, bacterial overgrowth, or other irritants within the diverticula. Symptoms often include abdominal pain, particularly in the lower left quadrant, fever, and changes in bowel habits.

In contrast, diverticulosis refers to the presence of these pouches without any inflammation or associated symptoms. Appendicitis involves the inflammation of the appendix, while colorectal cancer is a malignant growth in the colon or rectum. Each of these conditions has distinct pathophysiological mechanisms and clinical presentations, distinguishing them from diverticulitis, which specifically involves inflammation or perforation of diverticula.
