However, other unusual structures have been described such as ovarian in 2.9% of cases, urinary bladder in 0.36% [36], sigmoid diverticulum [37], appendix epiploica [38], Meckel's diverticulum [39], and even gallbladder [40]. The presence of a vermiform appendix is reported with an incidence of 1% [41], and, although rarely, the appendix may become inflamed (Amayand's hernia) [42].…”
