Abstract

Crohn's disease is an idiopathic inflammatory bowel disease. Multidedector computed tomography is used in diagnoses and the management of the intramural, murat and extramural components of the gastrointestinal tract pathologies. VVith unknown eti-ology, and has variabie responses to medical and surgical management. Barium studies and colonoscopy are the primary evaluation methods of the inflammatory changes of the mucosa; however, both of them provide little information on the extraintesti-nal extent of the disease. İn recent years, multidedector computed tomography became an important modality to evaluate the pathologic changes of the intraluminal, intramural, and mesenteric extent of the disease, and the attachment of the adjacent structures. Fourty-one patients (11 women, 30 men, age range 22-75 years, mean age 43.97 ± 13.96) with histological proven Crohn’s disease were examined with multidedector computed tomography. İn the computed tomography studies of 41 Crohn’s disease patients, segmental small bowel wall thickening were detected in 31 out of 41 cases (75.6%) , the thickening involved the terminal ileum were in 14 out of 41 (34.1 %) patients, and the different extends of the colonic wall thickening were detected in 21 out of 41 (51.2%) cases. Both small and large bowel loops were involved in 11 out of 41 (26.8%) Crohn’s disease patients. Abscesses were found in four out of 41 (9.7%) Crohn’s disease patients. Enlarged mesenteric lymph nodes were detected in 17 (41.4%) of them. Fistulas were detected in 8 out of 41 (19.5%>) patients, five of them ıvere enterocutaneus, two of them were enterovesical fistulas, and one was bilioenteric fistula. Perforation was seen in one of the patients and right hemicolectomy was performed.
