| description | Purpose: Computed tomography(CT) is an excellent noninvasive modality to evaluate bowel wall thickening.The aim
of our study was to evaluate CT appearance of bowel wall
thickening due to various benign and malignant conditions taking
into consideration pattern of attenuation, bowel wall thickness,
extent of lesion, symmetry of lesion and other associated CT
findings.
Materials and Methods: The prospective study was carried
out on 50 patients who underwent computed tomographic
evaluation of abdomen for suspicion of bowel pathology
based on ultrasonography, barium studies and/or clinical
grounds. The studies were conducted on Siemens ART and
GE High speed CT scanners. The examination was performed
as is done routinely for an abdominal scan with imaging done
from diaphragm to pubic symphysis in supine position with
the right lateral decubitus scans in selected cases for better
characterization of gastric antral and duodenal lesions. Oral,
rectal and intravenous (IV) contrast agents were administered.
The diagnosis was confirmed by cytology or histopathology
of any biopsy or surgical specimen. However, in cases where
surgery was not done, diagnosis was confirmed by clinical
response to medical treatment.
Results: Based on the various CT characteristics of abnormal
bowel wall thickening, sensitivity and specificity of classifying
a lesion as benign or malignant were calculated. Majority
of the malignant bowel lesions were showing the following
characteristics i.e. heterogeneous pattern of enhancement,
marked bowel wall thickening, asymmetry of the lesion and focal/
segmental bowel involvement. Overall, CT showed a sensitivity
of 97% and specificity of 93% in differentiating between benign
and malignant etiology of abnormal bowel wall thickening.
Conclusion: Due to its high sensitivity and specificity, CT is
an ideal imaging modality for differentiating between benign
and malignant etiology of abnormal bowel wall thickening.
Radiologists should be aware of the usefulness of specific CT
criteria of bowel wall thickening to better differentiate benign
lesions from malignant or potentially malignant lesions that
warrant further diagnostic evaluation. |
