Appendiceal duplication: a new case.

Duplication of the vermiform appendix is a rare malformation. Few than 100 cases have been reported worldwide. It is usually diagnosed incidentally during emergency appendectomies due to inflammatory processes in the cecal appendix. We report a case of a woman presented with clinical features typical of acute appendicitis and surgical exploration revealed a double appendix. The operating surgeon should be vigilant of these rare anomalies to avoid serious clinical and medico legal consequences.
