Computed tomography mimics of acute appendicitis: predictors of appendiceal disease confirmed at pathology.

The CT finding of fat stranding can be an important sign of acute appendicitis and may support the clinical diagnosis, when the appendix is not clearly visualized.[ 9 ] Stranding has been shown to have a sensitivity ranging from 87% to 100%, and as long as it is centered around the appendix, its specificity is between 74% and 80%.[ 17 , 20 ] Our findings echo those of previous reports, as the presence of peri-appendiceal inflammation was a strong, highly significant predictor of acute appendicitis, with an OR near 6.
