Hereditary colorectal cancer syndromes.

Radiological diagnosis of the inflammatory bowel disease (IBD), ulcerative colitis and Crohns disease, is establishing by plain abdominal philm, barium enema study and enteroclisis. Inspite of difficult radiologic differential diagnosis during advanced stage of the IBD (regarding similar radiological signs), in the early stage of the IBD radiological diagnosis can be reached using regular algorithm of the investigation and knowing and recognising early signs. We described differential basic radiological signs of both IBD.
