Thoracic ectopic kidney is a very rare developmental anomaly and the rarest form of all ectopic kidneys. We report a thoracic ectopic kidney in a 20 years old male.
Ultrasound examination and intravenous pyelography (IVP) revealed that no kidney was situated in the left renal region and pelvis. However, a left thoracic ectopic kidney was detected by renal scintigraphy easily.
Although it is extremely rare, the possible intrathoracic location of a kidney should be remembered when there is failure to demonstrate a kidney in the abdomen or pelvis.
