Objective: To study the imaging features of epiploic appendagitis. Methods and Materials: Clinical and imaging data of 24 patients diagnosed as epiploic appendagitis from 2009 to 2012 were studied retrospectively. Location, size, shape, density, surrounding inflammation and change of adjacent bowel wall were analyzed. Results: All of the lesions were solitary, appearing as round or oval lesions abutting colon wall, with density of fat inside and density of soft tissue of the border. Inflammatory infiltration was seen around all of the lesions, but no thickening of adjacent bowel wall was found. Thickening and exudation of adjacent peritoneum was seen in 17 cases. Conclusion: Characteristic clinical and CT features of epiploic appendagitis can help to avoid incorrect treatment.
