Appendiceal diverticulum diagnosed after appendectomy: Two case reports and literature review.

Introduction: Appendiceal diverticulitis is an uncommon pathology that imitates acute appendicitis and is usually treated by appendicectomy.

Cases presentation: We present two cases: a 50-year-old female patient and a 35-year-old male patient, both of whom presented with signs and symptoms of acute appendicitis and were managed accordingly. Final pathological examination confirmed the presence of an appendiceal diverticulum.

Clinical discussion: Diverticulitis of the appendix is four times more likely to lead to perforation when compared to appendicitis and may be associated with underlying neoplasm. Therefore, it is extremely important to distinguish diverticulitis of the appendix from appendicitis.

Conclusion: Clinicians should always consider appendiceal diverticulitis when evaluating patients with right-sided, lower quadrant abdominal pain.
