An unusual case report of a subhepatic appendix and an interlobar hepatic bridge in a patient with acute cholecystitis.

A subhepatic appendix and an interlobar hepatic bridge are both rare anatomical variants. To find both entities in the same patient at the time of a laparoscopic cholecystectomy makes for a unique case report. Subhepatic appendicitis has a reported incidence of 0.08%, and there have been only published three case reports of an interlobar hepatic bridge. Their lack of involvement in acute cholecystitis facilitated an easier dissection process and prevented serious complications to the liver or the right hemi-colon.
