Appendicolith

Dr Matt A. Morgan and Dr Jeremy Jones et al.

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 among patients with a retrocaecal appendix.

Pathology

Although the cause of appendicolith formation is uncertain, some case reports have mentioned an ingested foreign body or a dislodged gallstone eroding through the gallbladder as possible etiologies. 

Radiographic features

An appendicolith will cast an acoustic shadow at ultrasound examination and usually appears as a calcified nodule on an abdominal radiograph or CT examination. Up to 25% show laminated calcification.
