Significance of appendiceal thickening in association with typhlitis in pediatric oncology patients.

Background: The management of pediatric oncology patients with imaging evidence of appendiceal thickening is complex because they are generally poor surgical candidates and often have confounding clinical findings.

Objective: We sought to determine the significance of appendiceal thickening in pediatric oncology patients who also had typhlitis. Specifically, we evaluated the impact of this finding on the duration of typhlitis, its clinical management, and outcome.

However, vascular effects of the female sex hormone progesterone and the male sex hormone testosterone have also been suggested.
