Diverticulosis of the vermiform appendix of the colon is encountered infrequently in roentgenographic study of the intestinal tract. Whether discovery of these diverticula is important has yet to be determined. It is conceivable, however, that they might have clinical significance. It seems reasonable, therefore, for radiologists to keep this entity in mind and to mention its discovery with at least as much care as that accorded to diverticula in other portions of the alimentary canal. This report concerns two cases in which diverticula of the appendix were visualized in the course of radiologic examination of the colon by barium enema. The first was in a 51-year-old Negro mortician, referred for care because of addiction to Demerol, of two years duration. He had had numerous symptoms for which complete evaluation was undertaken.
