General considerations

  • Also known as a fecolith, fecalith, coprolith
  • Calcified deposit within the appendix
  • Present in approximately 30% of children with acute appendicitis
  • May be an incidental finding on an abdominal radiograph done for other purposes
  • But, when associated with abdominal pain, there is a 90% probability of acute appendicitis
    • Also 50% higher risk of appendiceal perforation
