Young women with no past surgical history presented with recurrent biliary colic. Abdominal ultrasound scan confirmed gallstones and she was listed for laparoscopic cholecystectomy. An incidental finding of an anterior sub-hepatic normal appendix was made during the operation. We are not aware of any previous normal sub-hepatic appendix images in the literature.
The presence of a sub-hepatic appendix is rare and usually retrocaecal. Palanivelu et al1 reported an incidence of 0.08% sub-hepatic appendix in 7210 appendicitis in India. Sub-hepatic appendicitis cases are usually missed preoperatively and only diagnosed at laparoscopy. Sub-hepatic appendicular abscess is the most reported presentation. Sub-hepatic appendicitis could easily mimic acute cholecystitis symptoms2 and the presence of fecalith could be mistaken for gallstones in an ultrasound scan examination.
