Does calcified appendicolith in appendix go away or just keep building up tell your appendix goes bad?

Good question.: It will not go away by itself. It does not require treatment unless you get appendicitis. And there is no known treatment. Not all appendicoliths result in appendicits, but no one knows how many. No one knows what fraction of acute appendicitis patients have appendicoliths (just that it is higher than normal) or how many patients with appendicoliths eventually develop appendicitis.
