Radiological findings in carcinoma of the colon complicating chronic ulcerative colitis.

There is now general agreement that neoplastic changes occur more frequently in the colon involved with ulcerative colitis than in the undiseased colon. We have reviewed the records of all patients with chronic ulcerative colitis and carcinoma of the colon seen at The University of Chicago hospitals and clinics to determine if there is any characteristic radiological appearance of the colon in those patients who subsequently developed a carcinoma and also to evaluate the gross radiological appearance of the tumours. The clinical and radiological findings also have been correlated.
