Acute single appendicitis in a female with a duplicated appendix

Abstract

Appendiceal duplication is a rare congenital anomaly with an estimated incidence ranging from 0.004 to 0.009%. Preoperative diagnosis of a duplicated appendix is often difficult and is usually done intraoperatively. Histopathological examination of the surgical specimen is mandatory to confirm the presence of two appendices. In this case we report a female patient with acute inflammation in one of her two appendices. Surgeons should always bear in mind this rare anomaly to avoid serious ethical and legal consequences.

Acute suppurative inflammation in dual appendix

“…The type B2 replication may be the vestige of a ''transient appendix'' which appears during the sixth and seventh week of embryological development according to most authors belief [5]. Most of the instances, other congenital anomalies are associated with type B1 and C [1]. Although duplication of the appendix may be related with other congenital anomalies, there were no other anomalies found in our case.…”

“…The appendix has many variations in their position and anatomy with rarely duplication and agenesis noted in the literature. Even though embryogenesis of the appendix is well known, the incidence of appendiceal duplication is not clear, ranging from 0.004%-0.009% [1].…”

“…Even though appendicitis is a common entity in surgical practice, the incidence of the dual appendix is rare which ranges from 0.004%-0.009% [1]. The dual appendix is an incidental finding intraoperatively which makes surgeon evaluate any associated anomaly.…”

Incidental finding of double appendix during laparotomy for intussusception: A case report

“…The complication of appendiceal duplications includes acute appendicitis [ [1] , [2] , [3] ], colonic perforation in case of colonic duplication [ 12 ], other complications include obstruction, bleeding, pain, failure to thrive, abdominal mass [ 9 , 13 ].…”

Bifid appendix: a case report and a review of literature

“…Ayoub et al . [8] also published an interesting case of a 30-year-old female who underwent open appendectomy for acute appendicitis. During surgery, two appendices on either side of the ileocecal valve were identified with acute appendicitis in only one of them which is consistent with a Cave–Wallbridge category B1 duplication.…”
