title: Helical CT evaluation of acute right lower quadrant pain: part II, uncommon mimics of appendicitis.
abstract: OBJECTIVE
  The purpose of our pictorial essay is to highlight the helical CT features of uncommon mimics of appendicitis and to provide clues to differentiate them from appendicitis.
  
  
  CONCLUSIONS
  Uncommon mimics of appendicitis create a diagnostic challenge in patients with right lower quadrant pain. Recognition of the helical CT features of uncommon mimics of appendicitis is important in clinical management and avoiding unnecessary laparotomy.
