Can colon cancer be mistaken for diverticulosis?


Can colon cancer be misdiagnosed as diverticulosis?

A number of patients with colon cancer have been misdiagnosed with inflammatory bowel diseases (IBD) such as irritable bowel syndrome, diverticulitis, and colitis. Other conditions such as hemorrhoids may also be misdiagnosed. Likewise, patients with these conditions may be misdiagnosed as having colon cancer.

Can colon cancer be mistaken for diverticulitis on CT scan?

One primary reason is because colorectal cancer may have been misdiagnosed as complicated diverticulitis when the original imaging was performed, especially if the diagnosis was based on CT imaging. Diverticulitis and colorectal cancer both present with colonic wall thickening on CT.

Does diverticulitis lead to colon cancer?

Diverticulosis may lead to several complications including inflammation, infection, bleeding or intestinal blockage. Fortunately, diverticulosis does not lead to cancer. Diverticulitis occurs when the pouches become infected or inflamed.

What can diverticulosis be mistaken for?

Common alternative conditions that can clinically mimic diverticulitis include small bowel obstruction, primary epiploic appendagitis, acute cholecystitis, appendicitis, ileitis, ovarian cystic disease, and ureteral stone disease.

What can be mistaken as colon cancer?

Colorectal cancer can seem a lot like some common gastrointestinal (GI) disorders, including hemorrhoids, irritable bowel syndrome (IBS), an infection, or inflammatory bowel diseases (IBD), such as Crohn’s disease or ulcerative colitis. They usually have many of the same symptoms.

What mimics diverticulitis on CT scan?

Primary colon carcinoma is the main consideration in the differential for findings of diverticulitis on CT (Fig. 10) because it may present with eccentric or circumferential wall thickening, varying degrees of inflammation, and signs of obstruction. Perforated colon carcinoma may mimic diverticulitis.

Should I have a colonoscopy if I have diverticulitis?

Your doctor may recommend colonoscopy six weeks after you recover from diverticulitis, especially if you haven’t had the test in the previous year. There doesn’t appear to be a direct link between diverticular disease and colon or rectal cancer.

Can you see colon polyps in a CT scan?

How are polyps diagnosed? Polyps are diagnosed by either looking at the colon lining directly (colonoscopy) or by a specialized CT scan called CT colography (also called a virtual colonoscopy).

How often should you get a colonoscopy if you have diverticulitis?

How often should you have a colonoscopy with diverticulosis? You’ll probably need a colonoscopy every 5 to 8 years if you have diverticulosis. Your doctor will let you know how often you need a colonoscopy if you have diverticulosis depending on the severity of your symptoms.
