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

Area of Science:

• Gastroenterology
• Surgical Innovation
• Pediatric Surgery

Background:

• A retained appendicolith is a rare complication following appendix rupture.
• It can lead to recurrent intra-abdominal abscess formation.
• This case highlights a unique presentation in a pediatric patient.

Observation:

• A pediatric patient experienced recurrent infections over 12 months.
• The appendicolith migrated unusually to the left abdomen.
• It subsequently penetrated the abdominal wall into subcutaneous tissues.

Findings:

• The retained appendicolith was the source of recurrent infections.
• Migration of the appendicolith was documented.
• Successful retrieval was achieved through a collaborative surgical and interventional radiology approach.

Implications:

• This case demonstrates an atypical migration pattern of a retained appendicolith.
• It underscores the importance of considering unusual presentations of appendicolith complications.
• Ultrasound-guided retrieval offers a minimally invasive option for managing complex cases.
