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

Crohn's disease is a chronic inflammatory condition of the gastrointestinal tract and is characterized by a few key features that differentiate it from other similar conditions, such as ulcerative colitis. Let's evaluate each of the provided statements to determine which one is not true about Crohn's disease:

1. Rectum is not involved: This statement is generally true. Crohn's disease can affect any part of the gastrointestinal tract from mouth to anus, often sparing the rectum.
2. Continuous lesion visualized in endoscopy: This statement is not true. Crohn's disease typically presents with 'skip lesions,' where patches of healthy tissue are seen between areas of inflammation, leading to a non-continuous pattern of disease.
3. Non caseating granulomas: This is true for Crohn's disease. The presence of non-caseating granulomas on histological examination is a hallmark but not always present in Crohn's disease.
4. Cobblestone appearance: This statement is true. Crohn's disease can cause the intestinal lining to have a cobblestone appearance due to deep ulcers and fissures intersecting inflamed mucosa.

Therefore, the correct answer to which statement is not true regarding Crohn's disease is: Continuous lesion visualized in endoscopy.
