An appendicolith is a calcified deposit within the appendix. They are present in a large number of children with acute appendicitis and may be an incidental finding on an abdominal radiograph or CT. Incidence may be increased amongst patients with a retrocaecal appendix.
An appendicolith will cast an acoustic shadow at ultrasound examination and appear as a calcified mass on an AXR or CT examination.
