Effect of Crohn's disease on colonic diverticula

Fifteen cases in which the same part of the colon has been affected by both diverticular disease and Crohn's disease have been studied. When Crohn's disease affects an area of colon where diverticula are present, radiological examination may show a diminution in number or disappearance of the diverticula with progress of the Crohn's disease. With improvement in the Crohn's disease diverticula may appear.
