Colonic diverticula. Radiological diagnosis.

Diverticulosis of the colon is the commonest organic disease found on barium examination of the large bowel. In a survey of the general population in the Oxford area one in three patients over 60 years of age was found to have diverticulosis.73 Most radiologists would agree with this figure, though there is certainly a wide variation in different population groups. Patients with large colons or redundant loops of sigmoid colon very seldom have demonstrable diverticula on barium enema examination. There has been considerable debate as to the correct nomenclature in this disease. In this paper the nomenclature used by G. T. Schmidt is followed72-that is, "diverticulosis" is used to describe the presence of colonic diverticula radiologically; "diverticulitis" is used when inflammation has occurred due to diverticulosis.
