Inflammatory/infectious diseases and neoplasms of colon. Evaluation with CT.
The purpose of this study is to review the computed tomography (CT) appearance of infectious and inflammatory diseases, and neoplasms of colon. Forty-five patients with 25 cases of colonic neoplasms and 20 cases of inflammatory and infectious diseases of colon were evaluated based on CT findings of colonic wall thickening (> 5 mm, soft tissue density versus pure wall edema or both), length of the involved segment (short (< or = 5 cm) versus long segment), pericolic infiltration, mesenteric infiltration, lateroconal fascial thickening, mechanical ileus, ascites, contiguous terminal ileum involvement, distribution of the diseased colon, and abscess formation. The results were compared using chi-square test or Fisher's exact test. Our results showed that colonic wall thickening of soft tissue density with or without edema and pure bowel wall edema were the two statistically significant findings in differential diagnosis of colon (p < 0.05). We concluded that CT is a good imaging tool to make differential diagnosis between infectious/ inflammatory diseases and neoplasms.
