[Radiologic findings on crohn's disease of the adult (author's transl)].

Roentgen signs of 42 patients with Crohn's disease are reported. Characteristic features are stenosis [30], fistulas (30), cobble-stone formation (14), asymetry of lesions (12), and thickening of the mucosal wall (10). Main locations are the ileum, predominantly its terminal part (32). The frequency of colon involvement has increased compared with earlier publications. 1 fistula between colon and urinary bladder is described as a rare type of tract formation. In comparison with a study of Hanke et al. (1978) in children there is no significant change in frequency distribution reported.
