Accuracy of noncompressive sonography of children with appendicitis according to the potential positions of the appendix.
This study evaluates noncompressive sonography of appendicitis in children according to the potential positions of the appendix. ⋯ The noncompressive technique is a valuable tool in sonographic investigation of appendicitis.

OBJECTIVE. We recently observed patients in whom the superior pericardial recess extended cephalad ("high-riding") into the right paratracheal region. ⋯ CONCLUSION. Narrow-collimation CT with multiplanar reformations was useful for confidently diagnosing a high-riding superior pericardial recess and for distinguishing it from pathologic lesions.

Appendicolith revealed on CT in children with suspected appendicitis: how specific is it in the diagnosis of appendicitis?
The purpose of this study was to determine the sensitivity, specificity, and positive and negative predictive values of a diagnosis of appendicitis when CT without enteric contrast material reveals an appendicolith in children with suspected appendicitis. ⋯ Although an appendicolith is significantly associated with appendicitis, the detection of an isolated appendicolith on CT is not sufficiently specific to be the sole basis for the diagnosis of acute appendicitis.
