Recurrent Iliopsoas Abscesses Due to Migrated Appendicular Fecalith

Case: Appendicular fecaliths have been reported to migrate to nearby organs before or during surgical treatment and become a late source of infection. We report an extremely rare case of recurrent iliopsoas abscesses caused by appendicular fecaliths that have migrated to the psoas muscle before or during the previous appendicectomy for acute appendicitis. In this case, surgical removal of fecaliths cured the iliopsoas abscess. Conclusion: Orthopaedic surgeons and gastroenterologists should remember that appendicular fecaliths that migrated into the iliopsoas muscle may cause late-onset iliopsoas abscesses.
