Variations in the position of the appendix, age of the patient, and degree of inflammation make the clinical presentation of appendicitis notoriously inconsistent. Statistics report that 1 of 5 cases of appendicitis is misdiagnosed; however, a normal appendix is found in 15-40% of patients who have an emergency appendectomy.

Niwa et al reported an interesting case of a young woman with recurrent pain in who was referred for appendicitis, treated with antibiotics, and was found to have an appendiceal diverticulitis associated with a rare pelvic pseudocyst at laparotomy after 12 months. [14] Her condition was probably due to diverticular perforation of the pseudocyst.
