1 Appendicitis

2 Pathophysiology Obstruction of lumen causes diffuse pain Intraluminal bacterial overgrowth causes: –Mucosal breakdown –Bacterial invasion of appendiceal wall –Inflammation --> peritonitis --> localized pain –Perforation E. coli, Peptostreptococcus B. fragilis, Pseudomonas

3 Technique IV contrast - 2cc/kg –Enhances inflammatory processes Helical (spiral) multidetector technique May use oral and/or rectal contrast

4 Enlarged Appendix Enlarged appendix (> 6mm diameter)

5 Enlarged Appendix Enlarged appendix (> 6mm diameter) 12mm

6 Appendiceal Wall Thickening Enlarged appendix (> 6mm diameter) Appendiceal wall thickening (>2mm)

7 Appendiceal Wall Thickening Enlarged appendix (> 6mm diameter) Appendiceal wall thickening (>2mm)

8 Wall Enhancement Enlarged appendix (> 6mm diameter) Appendiceal wall thickening (>2mm) Appendiceal wall enhancement

9 Wall Enhancement Enlarged appendix (> 6mm diameter) Appendiceal wall thickening (>2mm) Appendiceal wall enhancement

10 Fat Stranding Enlarged appendix (> 6mm diameter) Appendiceal wall thickening (>2mm) Appendiceal wall enhancement Periappendiceal fat stranding

11 Fat Stranding Enlarged appendix (> 6mm diameter) Appendiceal wall thickening (>2mm) Appendiceal wall enhancement Periappendiceal fat stranding

12 Appendicolith Seen in 20-40% of patients

13 Appendicolith Seen in 20-40% of patients
