Background: Appendiceal diverticulitis is a rarely diagnosed condition with an incidence of less than 2% in appendectomy specimens. Although first documented in 1893, recent documented cases have been rare. Case Report: This case report describes a 52 year old man presenting with appendicitis like symptoms, subsequently found to have perforated appendiceal diverticulitis on histopathology. Conclusion: Appendiceal diverticulitis should be considered as a differential in right iliac fossa pain. Progression of appendiceal diverticulitis is often insidious resulting in delayed presentations and subsequently higher incidences of perforation and mortality rates.
