Is thickening of the colon wall serious?

Focal, irregular and asymmetrical thickening of the bowel wall suggests a malignancy. Perienteric fat stranding disproportionally more severe than the degree of wall thickening suggests an inflammatory condition.

Is thickening of the colon wall common?

Bowel wall thickening is not an uncommon finding among patient undergoing abdomen CT scan.

Although specific radiologic patterns may direct to a precise diagnosis, occasionally misidentification may occur.

What is thickening of the colon on a CT scan?

Although asymmetric and heterogeneous focal thickening of the bowel wall usually indicates a malignancy, benign inflammatory conditions such as intestinal tuberculosis and Crohn’s disease may present with similar imaging features, sometimes mimicking neoplasms [3, 14, 15].

What can cause thickening of the colon wall?

Results The majority of those 27 reporting a history of IBS had thickening of the wall of the sigmoid colon. A cut-off of 3.0 mm gave a sensitivity for this group of patients of 70\%, specificity of 95\%, positive predictive value of 73\% and negative predictive value of 95\%.

Does gastritis show on CT scan?

In addition to gastric malignancies, CT can also help detect inflammatory conditions of the stomach, including gastritis and peptic ulcer disease. CT angiography is especially helpful for depicting the gastric vasculature, which may be affected by a variety of disease conditions.
