Diagnosis and Management of the Largest Documented Appendicolith in Literature: A Case Report.

This case report depicts the diagnosis and management of the largest documented appendicolith found in the medical literature so far, measuring 4.5 cm. A 44-year-old male patient presented with a distended abdomen, right lower quadrant (RLQ) pain, constipation, and the inability to consume solid food. Laboratory tests revealed leukocytosis and elevated C-reactive protein (CRP) levels. Abdominal X-rays showed a densely calcified structure in the right lower quadrant, and further imaging confirmed the diagnosis of appendicolithiasis. The surgical indication for appendectomy was determined, and an open surgical procedure was performed due to the severity of inflammation, minimal perforation, and extensive adhesions. The surgically removed appendix with the appendicolith was analyzed histologically, confirming appendicolithiasis, periappendicitis, perforation, and serositis. The patient was discharged in stable condition after postoperative management. Giant appendicoliths are rare and associated with an increased risk of complications. Diagnosis is typically clinical but can be enhanced by imaging modalities.
