Left-sided gallbladder:: calculous cholecystitis with situs inversus.

A 59-year-old woman with complete situs inversus, developed cholecystitis in a left-sided gallbladder. The diagnosis was made radiologically and a successful operation performed. A diseased gallbladder containing two calculi, together with the appendix, was removed. An operative cholangiogram revealed a normal, but transposed, biliary system. The literature on this subject is reviewed.
