Question

Which statement is not true regarding crohn's disease :

• A. Rectum is not involved
• B. Continuous lesion visualized in endoscopy
• C. Non caseating granulomas
• D. Cobblestone appearance

Answer 1

The Correct Option is B

Step 1: The task is to find the one option that contradicts the typical features of Crohn's disease.
Step 2: Crohn's classically produces patchy, discontinuous involvement - the so called skip lesions - with normal segments lying between diseased ones throughout the colon and small bowel.
Step 3: Calling the endoscopic picture continuous therefore describes ulcerative colitis, not Crohn's, so that statement is the false one.
Step 4: Rectal sparing, non-caseating granulomas and the cobblestone mucosa are all genuine Crohn's findings, confirming that the untrue statement is the continuous lesion on endoscopy.
\[\boxed{\text{Continuous lesion visualized on endoscopy}}\]
