Appendicitis and Situs Inversus Viscerum in a 32-year-old Female Nigerian: a Case Report

Situs inversus is a relatively rare congenital abnormality in which the internal organs are disposed in a mirror image of the normal. It is said to be an autosomal recessive genetic condition. Its prevalence varies with population. In the United States, Situs inversus is found in 0.01% of the population. The incidence in Nigeria is unknown. We present the case of a young lady with situs inversus discovered during management for appendicitis. As is often the case in situs situations, there was initial confusion and some significant delay in offering needed treatment due to the unusual disposition of the organs.
