Giant appendicolith: Rare finding in a common ailment

Area of Science:

• Gastroenterology and Surgical Oncology
• Diagnostic Imaging and Interventional Radiology

Background:

• Acute appendicitis is a common surgical emergency globally, with appendicoliths (calcifications within the appendix) present in approximately 10% of cases.
• While often asymptomatic, appendicoliths are associated with a higher risk of appendiceal perforation and abscess formation.
• Giant appendicoliths, defined as those exceeding 2 cm, are exceptionally rare clinical findings.

Observation:

• A young male presented with symptoms suggestive of appendicitis.
• Pre-operative diagnosis using Non-Contrast Computed Tomography (NCCT) identified a giant appendicolith.
• Intraoperative findings during laparoscopy confirmed a 3 cm appendicolith and an incidental Meckel's diverticulum.

Findings:

• The giant appendicolith was pre-operatively diagnosed as calcium struvite based on imaging characteristics.
• Surgical management involved appendectomy for the symptomatic appendicolith.
• The case underscores the diagnostic utility of CT in identifying rare appendiceal pathologies.

Implications:

• This case emphasizes the importance of considering rare presentations of appendicoliths, even in the absence of pathognomonic symptoms.
• Advanced imaging techniques like CT are crucial for pre-operative diagnosis of giant appendicoliths, aiding surgical planning.
• Further research into the composition and clinical significance of giant appendicoliths may improve patient outcomes.
