Intrathoracic kidney

An intrathoracic kidney is a very rare form of ectopic kidney. There has been no reported increased incidence of stones or infections as can be seen with other forms of ectopic kidneys. The adrenal glands are usually normal in location.

Intrathoracic kidneys are usually asymptomatic and detected incidentally during radiological workup.

Renal ascent to thoracic cage is limited by diaphragm. Diaphragmatic eventration or Bochdalek hernia can lead to an intrathoracic kidney 2.

  • appears as a well-defined lower thoracic opacity

The diagnosis can be easily confirmed by ultrasound. In most cases, the thoracic kidney rests on the diaphragm, so an acoustic window of the liver or spleen can be used to demonstrate it.
