Case Discussion

Situs inversus is a term used to describe the inverted position of the chest and abdominal organs.

Situs inversus is typically asymptomatic unless associated with congenital heart disease.

It falls into three main groups:

  • situs solitus: the normal configuration of thoracic and abdominal organs

  • situs inversus: mirror image of the normal configuration

  • situs ambiguus (heterotaxy): an intermediate configuration with duplication (isomerism)
