What is Underdistention mean?
Underdistention. — Underdistention of the colon leads to collapsed colonic segments. A colonic lesion located in a collapsed segment is not visible at either 2D or 3D imaging and will be missed.
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. It may be caused by neoplastic, inflammatory, infectious or ischaemic conditions but also be a normal variant. 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?
Inflammatory processes that may present as focal areas of bowel wall thickening include diverticulitis, appendicitis, and, occasionally, tuberculosis. A segmental distribution of involvement is usually caused by an inflammatory process.
What is wall thickening in the stomach?
The gastric wall thickening is a diagnostic challenge for gastroenterologists and can be caused by a wide variety of benign and malignant disorders including lymphoma, adenocarcinoma, Menetriers’ disease, Crohn’s disease, peptic ulcer disease, sarcoidosis and tuberculosis.
What are symptoms of bowel thickening?
Typical symptoms include several days of constant abdominal pain, most commonly in the left lower quadrant. Patients may also present with nausea, vomiting, low-grade fever, and/or change in bowel habits. Laboratory evaluation often reveals mild leukocytosis, but may be normal in up to 45\% of cases.
What causes bowel wall thickening?
Common causes of bowel wall thickening include edema, hemorrhage, infection, graft-versus-host disease, and inflammatory bowel disease; more unusual causes include immunodeficiencies, lymphoma, hemangioma, pseudotumor, and Langerhans cell histiocytosis.
Can IBS cause colon wall thickening?
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.
