Granulomatous disease of the intestinal tract (Crohn's disease).

In a landmark lecture on this disease, the author presents his experience with some 8,000 cases of regional enteritis and 4,000 of granulomatous colitis. The paper is divided into sections on the history, pathology, pathogenesis, roentgen findings, and course of the disease. The main thrust of the paper is the extensive roentgen analysis of granulomatous disease, with a discussion of differential diagnosis, especially from ulcerative colitis. Through the years, the author has been impressed with certain clinical and roentgen features of this malady (his Ten Principles of Crohn's Disease) which are carefully reviewed.
