AbstractObjective: To review the diagnostic power of various computed tomography (CT) signs in acute appendicitis, in particular those initially classified as inconclusive. Materials and methods: Retrospective review of 100 CT abdomen and pelvis studies with assessment of maximal luminal diameter, wall thickness and cross-sectional diameter of the appendix, periappendiceal inflammatory changes, and presence of appendicolith. Results: All CT signs show statistically significant occurrences in acute appendicitis. Their respective cut-off values with best sensitivity and specificity were calculated. Those from the inconclusive cases were also reviewed. Conclusion: Maximal cross-sectional diameter of the appendix is the most powerful parameter. Rest of the CT signs is supportive, especially in cases with inconclusive results. © 2012 Elsevier Inc.
