How Cobblestone Ulcers Help Doctors Diagnose Crohn’s
Cobblestone ulcers are a visible sign doctors rely on to tell Crohn’s disease apart from other IBD types, which can speed accurate diagnosis and the start of appropriate testing and treatment. The article also summarizes common symptoms and complications patients should know about.
People with suspected or diagnosed Crohn’s disease, newly diagnosed patients, adult patients considering colonoscopy, and clinicians evaluating suspected IBD.
What To Know
Doctors often use colonoscopy images to identify characteristic cobblestone ulcers, which help distinguish Crohn’s disease from ulcerative colitis. The article explains what cobblestone ulcers look like, why they form, other ulcer types seen in Crohn’s, and common tests used to diagnose and monitor the condition.
Cobblestone ulcers are groups of deep intestinal ulcers that can appear as patchy, raised areas and are commonly seen during a colonoscopy. Finding them supports a diagnosis of Crohn’s because Crohn’s tends to cause patchy, transmural inflammation, unlike the continuous, surface-level inflammation more typical of ulcerative colitis.
The main test discussed is colonoscopy; the article also reviews related procedures (upper endoscopy/enteroscopy), CT imaging, blood tests, and how biopsies are used to confirm diagnosis. It lists common symptoms and complications to watch for, such as anemia, fistulas, strictures, abscesses, and malnutrition.
If you’re having ongoing abdominal pain, diarrhea, or unexplained weight loss, your clinician may recommend a colonoscopy or other imaging and blood tests to look for ulcers and obtain tissue for testing.
This is a patient-focused overview explaining signs, tests, and complications; it’s not new research and does not change treatment recommendations. The article summarizes standard diagnostic approaches (colonoscopy with biopsy, endoscopy, CT, blood tests). For individual care decisions, consult a gastroenterologist.
