Erythematous Colon Mucosa (3 of 3)

Intradiverticular diverticulum. Some large diverticula can have a small "daughter", inside a sigmoid diverticulum. A diverticulum (if there are more than one they are known as "diverticula") is a protrusion of the inner lining of the intestine through the outer muscular coat, forming a small pouch with a narrow neck. The commonest site for diverticula to develop is the lower left part of the colon. The presence of diverticula is often referred to as diverticulosis. Most diverticula develop during later life and are more and more common with increasing age. But can form anywhere in the large intestine. Once these pouches form they remain for life but frequently cause no problems.
