Diverticulosis is the presence of diverticula, small sac-like outpouchings, in the wall of the colon. It is extremely common, especially in people over 50 years of age in Western countries, and most people with diverticulosis have no symptoms. On ultrasound, diverticula may sometimes be seen as small, round outpouchings from the colonic wall, and they may be incidentally noted during abdominal scans performed for other reasons. While diverticulosis itself is not dangerous, it can lead to diverticulitis if the pouches become inflamed, and to significant gastrointestinal bleeding if blood vessels in the diverticular wall rupture.
