Migrating appendicolith: A retained appendicolith causing recurrent infection and migrating to the skin

Abstract

A retained appendicolith is an uncommon complication that can arise from appendix rupture and can lead to recurrent abscess formation. We present a case of a retained appendicolith causing recurrent infection over a 12-month period in a paediatric patient. The appendicolith migrated to the left side of the abdomen and then through the abdominal wall into the subcutaneous tissues. The appendicolith was finally retrieved in a joint surgical and interventional radiology case using ultrasound guidance.
