Computed tomography findings of normal appendix in pediatric population
Review of abdominal CT scans from 358 children imaged for non-appendicitis indications found a mean normal appendiceal diameter of 5.00±1.09 mm. Means increased from 4.22 mm in infants to 5.83 mm at ages 15-18 and were associated with age and body-surface area. Age-aware interpretation is warranted, but diameter alone does not diagnose appendicitis.
