Where this comes from

Abstract

Our purpose was to retrospectively evaluate the cases of patients with surgically proven appendicitis that was misdiagnosed on abdominal CT to determine the causes of the missed diagnosis. Increased awareness of the underlying factors common to most cases of the missed diagnosis of appendicitis on CT and increased radiologic vigilance in cases of atypical abdominal pain may enable us to further improve our diagnostic accuracy.
