[X-ray diagnosis of Crohn's disease in the region of the colon (author's transl)].

The article reviews the catalogue of signs visualized on x-ray film in colitis granulomatosa Crohn, underlining the typical changes such as segmental involvement, right-sided colitis, preferential involvement of that part of the wall of the colon which is close to the mesentery, pronounced tendency to fistula formation, as well as the various forms of mucosal lesions. Attention is drawn to the possibility of roentgenologic differentiation between colitis granulomatosa Crohn and colitis ulcerosa. The individual signs of both diseases are compared with each other in tabular form.
